Momentum Source-User Defined Function

mohammad · November 4, 2019, 00:17

Hi everybody,

I am trying to simulate a domain inside which an area has fixed pressure.
I know how to apply momentum source. Also I know how to fix a cell value (as it is explained in :
[Swiss STAR-CCM+ Knife: [1] Big Sources: How to override equations and fix cell physical values].

However, the problem in that the above method can be applied for a vector parameter such as velocity.

My question is that how should I use a similar method or any other method to fix a pressure values over a certain location inside my domain.?

Regards,
