I am using a 2D udf for velocity at Inlet. aftre compiling it using

the message coming is

cpp: output pipe has been closed

and it is not showing udf in the velcity_inlet panel. Plz suggest me is this an error

Have you successfully compiled other UDFs before?

The most likely cause is that there is an error in your source code. I have found the supplied cpp being quite useless when it comes to providing meaningful error messages (even compared to other c compilers)

Maybe you could post your UDF file? These things are normally blindingly obvious to people who haven't spent hours staring at the file already ;-)

Thnks Rob,

There was some problem with the file uploading from PC to unix system, so the file has got damaged during uploading. I got the solution.
