Hello

I want to inject a body force in a fluid flow domain. ( steady flow, body force depends on x and y)

My interpretation has been successfully done.

For information, I could run to model without udf code ( Only for boundary condition)

What should i pay more attention to  fluent setting , especially for  difference between simple model (without udf code) and with a udf code :

·          General

·          Models

·          Cell Zone

·          Boundary Condition ()….

·          Solution Initialization

        Run Calculation

Thank you for your reply

My question is How can I set up the fluent (difference between a simulation with code and without code in fluent setting).

I can't take a correct setting with a udf code.

thank you

If you want to add a body force you will then require some momentum source terms which can be done either via UDF or with Fluent Expressions.

 Thank you sir

My udf's code has been successfully interpreted and hooked.

i ask about fluent setting up other than udf code:

·          General

·          Models

·          Cell Zone

·          Boundary Condition ()….

·          Solution Initialization

 

Thank you
