README_USERD_2.03
=================
At this API revision level:
1. Routines to handle materials have been added.
2. Routines to handle nsided and nfaced elements have been added
3. A routine has modified so structured ranges can be specified
****************************************************************************
Note: The dummy_gold reader, the Ensight Gold example reader, and the
SILO reader have been moved to this 2.03 API level.
****************************************************************************
-------------------------------
Quick Index of Library Routines
-------------------------------
The new new routines are:
-------------------------
USERD_get_number_of_material_sets Gets the number of material sets
USERD_get_matf_set_info Gets the material set indices and names
USERD_get_number_of_materials Gets the number of materials
USERD_get_matf_var_info Gets the material indices and descriptions
USERD_size_matf_data Gets the length of either the
material ids list,
mixed-material ids list, or
mixed-material values list
USERD_load_matf_data Gets the material ids list,
mixed-material ids list, or
mixed-material values list
USERD_get_nsided_conn Gets the element connectivities for nsided
elements. (utilizes the number of nodes
per element obtained in
USERD_get_part_elements_by_type)
USERD_get_nfaced_nodes_per_face Gets the number of nodes per face for nfaced
elements (utilizes the number of faces
per element obtained in
USERD_get_part_elements_by_type)
USERD_get_nfaced_conn Gets the element connectivities for nfaced
elements (utilizes the number of nodes
per face obtained in
USERD_get_nfaced_nodes_per_face)
The modified routine is:
------------------------
USERD_get_gold_part_build_info Gets the info needed for part building
process
--------------------
Header files changes
--------------------
global_extern.h has appropriate changes, must use it
global_extern_proto.h new file, access from global_extern.h
Basically the the old global_extern.h file has been split into two files now.
-------------------------
Order Routines are called
-------------------------
The various main operations are given basically in the order they will
be performed. Within each operation, the order the routines will be
called is given.
10. To see if materials in the model
USERD_get_number_of_material_sets
If any material sets in the model (calls these once per material set):
USERD_get_matf_set_info
USERD_get_number_of_materials
USERD_get_matf_var_info
For each elment type of each part containing material ids, calls:
USERD_size_matf_data
USERD_load_matf_data
If there are any elements with mixed materials, when a domain or
interface is created, calls these again per part:
USERD_size_matf_data
USERD_load_matf_data
6. Part building (per part created)
both unstructured and structured:
--------------------------------
USERD_set_time_set_and_step
if unstructured part:
--------------------
USERD_get_part_element_ids_by_type
USERD_get_part_elements_by_type
If any nsided elements:
USERD_get_nsided_conn
If any nfaced elements:
USERD_get_nfaced_nodes_per_face
USERD_get_nfaced_conn
USERD_get_part_coords
USERD_get_part_node_ids
.
.
.
-----------------------
Detailed Specifications
-----------------------
Include files:
--------------
The following header file is required in any file containing these library
routines.
#include "global_extern.h"
*******************************************************************************
****************************** Special Note ***********************************
*******************************************************************************
Make sure you use the proper define in the global_extern.h header file, namely:
#define USERD_API_203
Also, Make sure the api version in the USERD_get_reader_version routine is set
to "2.03" or larger.
Make sure your reader has access to the global_extern_proto.h This is a new
file which is access from the new global_extern.h

USERD_get_number_of_material_sets -
Description:
-----------
Get the number of material sets in the model
Specification:
-------------
int USERD_get_number_of_material_sets( void )
Returns:
-------
Num_material_sets = number of material sets
(Zero would indicate that you have no materials
to deal with in the model)
or
-1 if an error condition
Arguments:
---------
none
Notes:
-----
* You may want to keep this as a global for use in other routines.
###############################################################
NOTE: For EnSight 7.6, only one material set is supported
within EnSight.
Thus the only valid returns here are:
0 (no materials)
1 (for the one material set allowed)
or -1 (if an error)
If the casefile has more than this, this reader will
read them, but EnSight will issue an error message and
choke on them!
###############################################################
================================================================
A very simple explanatory example, to use as a reference for the
materials routines:
Given a 2D mesh composed of 9 quad (Z_QUA04) elements, with two materials.
Most of the model is material 1, but the top left corner is material 9 -
basically as shown:
*--------*--------*--------*
| | / | |
| Mat 9 / | |
| | / | |
| |/ | |
| e7 / e8 | e9 |
| /| | |
| / | | |
| / | | |
*----/---*--------*--------*
| / | | |
| / | | |
| / | Mat 1 |
|/ | | |
| e4 | e5 | e6 |
| | | |
| | | |
| | | |
*--------*--------*--------*
| | | |
| | | |
| | | |
| | | |
| e1 | e2 | e3 |
| | | |
| | | |
| | | |
*--------*--------*--------*
Thus, in this routine, set:
Num_material_sets = 1
In USERD_get_matf_set_info, set:
mat_set_ids[0] = 1
mat_set_name[0] = "Material Set 1" (or whatever name desired)
In USERD_get_number_of_materials, input would be set_index = 0, and
would need to set:
Num_materials[0] = 2
For simplicity, the ids and descriptions that would be returned in
USERD_get_matf_var_info could be:
mat_ids[0] = 1
mat_ids[1] = 9
mat_desc[0] = "mat 1" (or whatever desired)
mat_desc[2] = "mat 9"
The per element material ids list would need to be:
material ids:
-------------
ids_list[0] = 1 (material id 1, for elem e1)
ids_list[1] = 1 ( " e2)
ids_list[2] = 1 ( " e3)
ids_list[3] = -1 (negative of index into mixed-material id list, for elem e4)
ids_list[5] = 1 (material id 1, for elem e5)
ids_list[5] = 1 ( " e6)
ids_list[5] = -5 (negative of index into mixed-material id list, for elem e7)
ids_list[5] = -9 ( " e8)
ids_list[5] = 1 (material id 1, for elem e9)
Finally we need the mixed material ids list and the mixed materials values list,
which would need to be:
mixed-material ids:
-------------------
==> 1 ids_list[0] = 2 (the -1 in the material variable points here,
2 indicates that two materials are present)
2 ids_list[1] = 1 (1st material is 1)
3 ids_list[2] = 9 (2nd material is 9)
4 ids_list[3] = -1 (negative of index into mixed-material val_list)
==> 5 ids_list[4] = 2 (the -5 in the material variable points here,
2 indicates that two materials are present)
6 ids_list[5] = 1 (1st material is 1)
7 ids_list[6] = 9 (2nd material is 9)
8 ids_list[7] = -3 (negative of index into mixed-material val_list)
==> 9 ids_list[8] = 2 etc.
10 ids_list[9] = 1
11 ids_list[10] = 9
12 ids_list[11] = -5
mixed-material values:
----------------------
==> 1 val_list[0] = 0.875 (the -1 in the mixed-material ids_list points here,
and this is the value for material 1)
2 val_list[1] = 0.125 (the value for material 9)
==> 3 val_list[2] = 0.125 (the -3 in the mixed-materials ids_list points here)
4 val_list[3] = 0.875
==> 5 val_list[4] = 0.875 (the -5 in the mixed-materials ids_list points here)
6 val_list[5] = 0.125
So, USERD_size_matf_data would need to return
matf_size = 8, when called with set_id = 1
part_id = 1
wtyp = Z_QUA04
mat_type = Z_MAT_INDEX
matf_size = 12, when called with set_id = 1
part_id = 1
mat_type = Z_MIX_INDEX
= 6, when called with set_id = 1
part_id = 1
mat_type = Z_MIX_VALUE
And, USERD_load_matf_data would need to return:
the int array ids_list as shown above when called with:
set_id = 1
part_id = 1
wtyp = Z_QUA04
mat_type = Z_MAT_INDEX (indicating id list).
the int array ids_list as shown above when called with:
set_id = 1
part_id = 1
mat_type = Z_MIX_INDEX (indicating id list).
the float array val_list as shown above when called with:
set_id = 1
part_id = 1
mat_type = Z_MIX_VALUE (indicating val list).

Description:
-----------
Gets the array containing the connectivity of nsided faces of nfaced elements
Specification:
-------------int
int USERD_get_nfaced_conn(int part_number,
int *nfaced_conn_array)
Returns:
-------
Z_OK if successful
Z_ERR if not successful
Arguments:
---------
(IN) part_number = the part number
(OUT) nfaced_conn_array = 1D array of nsided face connectivies of nfaced
elements
(int array will have been allocated long enough to
hold all the nsided face connectivities. Which is
the sum of all the nodes per face values in the
nfaced_npf_array of USERD_get_nfaced_nodes_per_face)

USERD_get_gold_part_build_info
Description:
-----------
Gets the info needed for part building process
Specification:
-------------
int
USERD_get_gold_part_build_info(int *part_id,
int *part_types,
char *part_description[Z_BUFL],
int *number_of_nodes,
int *number_of_elements[Z_MAXTYPE],
int *ijk_dimensions[9],
int *iblanking_options[6])
Returns:
-------
Z_OK if successful
Z_ERR if not successful
Arguments:
---------
(OUT) part_id = Array containing the external part
ids for each of the model parts.
IMPORTANT:
Parts numbers must be >= 1, because
of the way they are used in the GUI
*******************************************
The ids provided here are the numbers by
which the parts will be referred to in the
GUI (if possible). They are basically
labels as far as you are concerned.
Note: The part numbers you pass to routines
which receive a part_number or block_number
or which_part as an argument are the 1-based
table index of the parts!
example: If Numparts_available = 3
Table index part_id
----------- -------
1 13
2 57
3 125
^ ^
| |
| These are placed in:
| part_id[0] = 13
| part_id[1] = 57
| part_id[2] = 125
| for GUI labeling purposes.
|
These implied table indices are the part_number,
block_number, or which_part numbers that you would
pass to routines like:
USERD_get_part_coords(int part_number,...
USERD_get_part_node_ids(int part_number,...
USERD_get_part_elements_by_type(int part_number,...
USERD_get_part_element_ids_by_type(int part_number,...

USERD_get_block_iblanking(int block_number,...
USERD_get_block_ghost_flags(int block_number,...
USERD_get_ghosts_in_block_flag(int block_number)
USERD_get_border_availability( int part_number,...

Z_MAXTYPE long)
(OUT) ijk_dimensions = 2D array containing ijk dimension info
for structured blocks
For Z_UNSTRUCTURED - is ignored
For Z_STRUCTURED or Z_IBLANKED
Prior to version 2.03:
----------------------
(Array will have been allocated
Numparts_available by 3 long)
ijk_dimensions[][0] = I dimension
ijk_dimensions[][1] = J dimension
ijk_dimensions[][2] = K dimension
Starting at version 2.03:
------------------------
(Array will have been allocated
Numparts_available by 9 long)
There are two ways to do this:
------------------------------
1. The simple one, without ranges.
This is good for all structured models
that will NOT be used in EnSight's
Server of Servers
Simply provide the ijk dimensions in the
first three slots and place a -1 in
the 4th slot. (The remaining slots will
be ignored).
Thus,
ijk_dimensions[][0] = I dimension of block
ijk_dimensions[][1] = J dimension of block
ijk_dimensions[][2] = K dimension of block
ijk_dimensions[][3] = -1
(J planes)
4 *-------*-------*
| | | ijk_dimension[0][0] = 3
| | | ijk_dimension[0][1] = 4
| | | ijk_dimension[0][2] = 1
3 *-------*-------*
| | | ijk_dimension[0][4] = -1
| | |
| | |
2 *-------*-------*
| | |
| | |
| | |
1 *-------*-------*
1 2 3 (I planes)
2. Using ranges.
This one can be used anytime, but MUST
be used if EnSight's Server of Servers
is to be used!
The first 3 slots contain the ijk dimension
of the complete block (of which this may be
a portion). The last 6 slots contain the
ijk min and max ranges within the complete.
Thus,
ijk_dimensions[][0] = I dim of complete block
ijk_dimensions[][1] = J dim of complete block
ijk_dimensions[][2] = K dim of complete block
ijk_dimensions[][3] = Imin of portion (1-based)
ijk_dimensions[][4] = Imax of portion (1-based)
ijk_dimensions[][5] = Jmin of portion (1-based)
ijk_dimensions[][6] = Jmax of portion (1-based)
ijk_dimensions[][7] = Kmin of portion (1-based)
ijk_dimensions[][8] = Kmax of portion (1-based)
example1: (Model has one part, a simple 2D block,
and want whole thing)
(J planes)
4 *-------*-------*
| | | ijk_dimension[0][0] = 3
| | | ijk_dimension[0][1] = 4
| | | ijk_dimension[0][2] = 1

| | | ijk_dimension[0][3] = 1
| | | ijk_dimension[0][4] = 3

| | | ijk_dimension[0][8] = 1

. . . ijk_dimension[0][7] = 1
. . . ijk_dimension[0][8] = 1

And note that if you were partioning this block for
EnSight's Server of Servers, you would only have one part,
instead of two. Each SOS server would return its appropriate
ranges in the last 6 slots. The first 3 slots would remain constant.
(OUT) iblanking_options = 2D array containing iblanking
options possible for each
structured model part.

(Ignored unless Z_IBLANKED type)

Notes:
-----
If you haven't built a table of pointers to the different parts,
you might want to do so here as you gather the needed info.
This will be based on Current_time_step
