  //   - Must recreate block/set id array.
  // - Has requested time changed?
  //   - If so, AND if "deflect mesh" turned on, must load new deflections and compute new points.
  //   - If so, must assemble all time-varying arrays for new time.
  // - Has array status changed?

  // changed and then toss them out in order to load arrays for a

  // Caching strategy: use GLOBAL "object type" for assembled arrays.
  // If connectivity hasn't changed, then these arrays can be used;

  //   - single cache == easier bookkeeping (two caches would require us to decide how to equitably split avail mem between them)
