A <A HREF="../DM/DM.html#DM">DM</A> can only be used for solving one problem at a time because information about the problem is stored on the <A HREF="../DM/DM.html#DM">DM</A>,
even when not using interfaces like <A HREF="../SNES/DMSNESSetFunction.html#DMSNESSetFunction">DMSNESSetFunction</A>(). Use <A HREF="../DM/DMClone.html#DMClone">DMClone</A>() to get a distinct <A HREF="../DM/DM.html#DM">DM</A> when solving different
problems using the same function space.
