Hi guys,
First, I interpreted a UDF in Fluent 16 and during the calculation it shows the following message ( but the calculation goes on without any intruption)
chip-exec : UDF: argument 5: incorrect type (0) int pointer expectedchip-exe

I don't know what is this about.

Second, I want to load a udf for certain time in my calculations and after that i want to continue my calculation with another udf, i encounter with somthing like "signal fatal error"?!!! I don't know how to load a udf for some time steps and another one for the other time steps

I wonder if anyone can help me especially with the second one.
thanks
