UDF Error
 

I'm using an interpr. UDF in my unsteady calculation. it works fine and the unsteady velocity is recognized in the BC.

when I'm running it in background, Fluent can not find the file, I guess, as it complains of not finding "unsteady_velocity" ...... is it because I need to store the file where the batch scheduler copies the case and data files ? I'm using an absolute path name for the UDF C file.

any suggestions ?
