Hi Joel,

Thanks for pointing out the bug with restarts for moving grids.

The attached tar file contains fixed versions of
  cg/common/moving/src/MovingGrids.C
  cg/common/moving/src/RigidBodyMotion.C
that hopefully will fix the problem. You will need to regenerate
the show file that you use for restarts.

Hi,

I'm trying to restart a moving body simulation on cg.v22, but I'm getting this

With the previous version (overblown) I had no problems restarting a moving 
body simulation.  Any idea of what could be the problem????  What are the 
possible sources of this error?

Joel
