Just curious, Writers_Block, are you trying to re-sim the created mesh with extension _VWD, and without changing that extension (to anything else - _01, _sim1, etc)?

Every time you call VWD it will create a new mesh with extension _VWD for simulation. My understanding (and usage) was that to re-sim, this needed to be changed, and you work from iteration counts.

Smaker1:

Same question for you - are you saying you are able to re-sim same mesh (_VWD) again, and again without creating iteration meshes?
