  Hi everyone!. Ia have been trying to compile a UDF in ANSYS Fluent but I get this error:
  (chdir "libudf")(chdir "win64\3d_node")"nmake" no se reconoce como un comando interno o externo, programa o archivo por lotes ejecutable.
  I think this error is given by the compiler but I do not know hot to solve it. Can anyone help me?

    Thank you very much. I installed Visual Studio Professional 2015 and was able to compile the UDFs.
