hi all.

when i import any udf,FLUENT tell there is an "parse error".that is,my FLUENT can not understand "#include<udf.h>",and can noe find the headfile of udf.i don't know the reason. pls help. thanks in advance!!

that is because FLUENT does not recognise the presence of the file in that particular direcory.

type the full path name of the file and see if that works out.

another problem may be that you are not saving your udf as a header file.FLUENT does not accept the udf if you save it as a text file. save it as a .h file. I hope that solves your problem
