[overture] Re: Version 23 released

Bill,

  Thanks for the updates.  I have a couple of questions:

 1: You said  (userDefinedMotion.C) the object params has been renamed
to parameters. I made some changes in the userDefinedMotion.C, can I
still use the modified subroutine in the new version?

 2: Will cgmp consider the viscosity change with the temperature? I
made the change in cgins before.

Thanks,
 Yongsheng
