How to add body force in CFX5.5
 

Hi all! If I want to add body force, such as gravity and Lorentz forcce, to the fluid, how can I put it into practice in CFX5.5? By using CEL or subroutine?

Best regards!

Gravity can be added by specifying buoyancy in the Domains form. General body forces can be added with momentum source terms (and perhaps CEL).

Thank you Robin! Yes, I should creat a sub-domain! Thank you again!

Best regards!

Hi Robin!

I want to know how to add gravity by specifying buoyancy? Another question is how to use sub-domain to add general body force with momentum source terms. Can you give me guildlines? Thank you!

Best regards!
