Usage of C_T_M2 creating problems

Sorabh · March 19, 2019, 01:50

Hello, again.

I am writing a udf where I need the value of temperature of a cell 2 timesteps before. I use C_T_M2 for this, and C_T_M1 for the value at previous timestep.

I activated a user-defined Scalar (UDS) as mentioned in the manual.

However, on hitting the calculate button, Fluent exits with the following error

Code:

9999999: mpt_accept: error: accept failed:	Invalid arguement
MPI application rank 0 exited before MPI_Finalize() with status 2

However, if I don't use the C_T_M2, then the calculations run smoothly.

What could have gone wrong? Could anyone please help me out??

how could you get C_T_M2 value on the first iteration (timestep)?

best regards
