Dear fluent-users,

I am using Ansys-fluent 15.0.0 to carry out a parametric simulation with design explorer and surface response. I need to pass two of the parameters to an UDF and I define them as "Use in UDF" in the parameter window. Then, in the UDF file I read them by


real k=RP_Get_Input_Parameter("real-1");


This works, and the value of the parameter can be read in the UDF.

But when I define a second parameter and try to read it too by


real n=RP_Get_Input_Parameter("real-2");


after running the udf, fluent says


Error: received a fatal signal (Segmentation fault).

Did anybody have this problem before?
If so, or you have any idea to solve it, please, let me know it.

Thanks in advance.

Regards.

Hi jortega,

I have the same problem. Would you please tell us about the step-by-step process of how you solved it. I couldn't get the procedure in the link to work.

Also I wanted to know if you have contacted Ansys tech support about this?

Thanks,
MSNJ3

Hi MSNJ3,

I just followed the steps given in the link and it worked.

I didn't contact with ANSYS tech. support. Maybe you should do it. If so, please, let us know what they say.
