I'm running a two-way FSI simulation (with blood and a group of vessels). I start ANSYS using Visual Studio, run SC, pause it, then go to Fluent to load my UDF, and continue the calculation. But I get an error message from SC and Fluent. 

I tested my UDF in CFD before, and it worked fine. Can you help me fix this issue? Thanks!

Is it failing while restarting the solution?

Which participants are being used in this coupling study?
