hi all,

when i try to set up the compiled udf library by following the instruction for windows NT the system gives me an error message as follows, fatal error U1050: you need to define the environmental variable FLUENT_INC. iam not familiar with vc++, so anyone who has encountered this before can u please help me. thanks for the help in advance. siva

You need visual studio 6 and in order to compile you need to set your environment variables selecting the item from the start menu, ie start -> programs -> Fluent.Inc -> Environment Variables. (or whatever it is)

Then run the vcvars32.bat batch file from the cmd prompt located in the bin folder of c++. Then you can run nmake to compile.

Look at the documentation Fluent have provided! There is a .pdf file which explains this!
