      Hi All, 


      I'm using a shear rate dependent vscosity for my simulations. My UDF work if I just take a constant value for the shear rate, but if I use a variable it gets this error: ' MPI Application rank 0 exited before MPI_Finalize() with status 2 ' and then fluent closes.


      I use a C_UDMI macro and I have enabled the memory in fluent, and I defined also the excute at he end in fluent.

      Just use the strain rate directly in the property UDF. Disable writing first as is not required.
