I have a simulation, in which the case file was created in Ansys 19.1. When I try to load it in v. 19.2 (the version I have), I get this warning when the library is loaded and auto-compiled. 

Online comments tell me that a possible reason for this is version mismatch and that I should delete the old library and compile the udf in the new version of Fluent. I have tried doing this a couple times and still receive the same error messages.

The compiler I am using is Visual Studio 2017 with the 64-bit compiler.

Best,

Claire

It looks to be compiling OK, can you retry in serial?

 

 

[rachels1001]

I generally need to run in parallel because of the computation time of the simulation. I tried running it in serial just now and the system automatically reverted back to parallel. 

I got the same error again running with a different simulation, and so I believe it's a problem with my compiler. I have tried uninstalling and reinstalling Visual Studio 2017.

I don't think it's the compiler as that would report an error when compiling the code. Always test on a small model, this will also help identify if it's a problem with the UDF or that particular case.

I tried running fluent with a couple other simulations that used UDFs and I kept getting the same error. Eventually I just uninstalled and re-installed Ansys, and it is compiling properly now.

Nice. Can you then mark this thread as "is Solved". Thanks!
