Has this been resolved ?
I seem to have the same issue with ANSYS 21R2 Fluent. I was unsuccessful with clang (inbuilt compiler), visual studios (19 and 22), and the standalone bootup. The compilation process begins, creates a libudf folder inside the FFF folder, which misses the libudf.dll file. I previously have run the same udf sequences on ansys 21R1 and everything worked fine.
