problem with Time Derivative function
 
Hi,

I'm solving a multicomponent problem (on CFX 12.0), and the following error message appears on the first interation:

Details of error:- ----------------
Error detected by routine PSHDIR
CDRNAM = TIMEDERIV
CRESLT = NONE



ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| Stopped in routine MEMERR

Anybody know what is this? I know the error occurs with time derivative function, but how can I solve it?

Increase the allocation factor not resolve the problem!

No idea. Usually this type of error is caused by some missing information, maybe a material property or a factor a particular physics model needs. Have a look at all the physics models you have (you are using a multi-component model so you have to have a few) and check anything dealing with time or time constants is correctly defined.
