Missing math.h header
 

I'm trying to compile a UDF, but FLUENT is missing the math.h header file. Where can I download it?

Re: Missing math.h header
 

Hi Travis, You have included udf.h in your udf ?

You can find math.h in google !!!

Re: Missing math.h header
 

I have included udf.h, and that parses fine. I tried looking for math.h on google and only got descriptions of it, no downloads. Did you find it? Thanks!

Re: Missing math.h header
 

Here is a copy of my math.h file, copy it and paste it in a wordpad file and save it as math.h:
