UDF and previous time step macros
Hi! I need to get pressure values from previous time step. I try to use the C_P_M1 macros. But I see: "fluent.6 received a fatal signal (SEGMENTATION VIOLATION)". Why? Help!

Re: UDF and previous time step macros

Please try to the following command on Fluent text prompt before iterations.


Keep temporary solver memory from being feed?[no] yes

Maybe it will be O.K. If this command doesn't be carryed out , Fluent doesn't store this kind of macros.

Thank you

Hi Aleex

I have faced with a problem like yours, I use C_P_M1(c,t) but I recieve an error.
I know your Massage was about 6 years ago but i hope to give an answer from you. Did you solve your problem in that time? How?
