Question on USER_GETVAR

Shaowei

Hi! I use USER_GETVAR in CFX5.6 to get the gradient of a variable and pass a quantity calculated with the gradient to the source of another transport variable. There is no problem. But when I pass the quantity to the third algebraic variable an error occurs.

The error message is bellow:

Details of error:- ---------------- Error detected by routine PSHDIR CDRNAM = GRADIENT CRESLT = NONE +-------------------------------------------------------------------+ | Writing crash recovery file | +--------------------------------------------------------------------+ Details of error:- ---------------- Error detected by routine MAKDAT CDANAM = LVAR CDTYPE = INTR ISIZE = 46 CRESLT = OLD

What's the problem? So weird! Many thanks!
