UDF help!
 

I need to write a udf to take a species mass fraction at an outlet and apply it at an inlet for a unsteady problem with the velocity field already solved for. Ive never written a UDF! Im trying to learn how to use them with the udf manual, but Im getting: parse error line 1 when i copy the samples in the udf manual! What do I do? Please help! Thanks soooooo much. Richard

Re: UDF help!
 

Save the UDF, with extension ".c", in the same file that u have the working files. Sometimes is the reason for that error.
