Hi all, I'm working on the unsteady compressible flow in a nozzle.I have attained a steady state solution and would like to set the conditions for unsteady solution.Can anybody help me with compilation and interpretation of UDF's for this case? Thanks, -kiran

Hi Kiran,

you should write a UDF using macros defined for particular vector or scalar variable and store it in src folder in home directory for your Fluent code. you can access this macro from Fluent window in File menu. you should not forget .c extension to signify C like code structure for your UDF.

Hi, Thanks swarup for your reply.I'll try that and get back if I have any more questions.Thanks again!! Regards, -Kiran
