run problem
 

Hi every body
I have the same problem in each udf that I write
I write my udf (e.g. for the inlet velocity profile), compile it successfully and hook it. but when i want to run fluent, it doesn't work (fluent doesn't apply the profile) and even it gives me no values for flow variables. i had this problem with a source term before and i couldn't find its solution.

what should i do?

Please upload your code.

I think this is initial value problem.

unless your code is wrong Even though you compile, hook successfully,

it's not work

sorry for poor english
