[CIG-SHORT] TimeStepUser

[Brad Aagaard]

Birendra,

I used the exact settings you specified with examples/3d/hex8/step19.cfg 
and the time stepping proceeds correctly. I suggest using pylithinfo to 
check to see what parameters PyLith is using. You may be inadvertently 
overwriting your settings with settings in another file.

Regards,
Brad
