hi everyone
I want to compile a mass inlet udf for boundary condition. I run fluent through microsoft VS 2010. I also copied the fluent.exe address in environmental variable path. the udf is compiled in another system with these conditions. but I in my system I face the following error while compiling it. I will be really thankful if anyone could help me with this problem.
