FLOEFD does not see the flow

denizcancinar · August 29, 2024, 04:41

Hello everyone,

There is a problem with my desired flow. Normally the flow should be gone by starting of the valve to the end. You can see the attached image 1. Computational domain is created by software and it is not that I want to. Tried to edit computational domain but I have faced an error with the boundary conditions. As can be seen in the image 2 the fluid actually goes through all geometry.

What could be the problem? Thanks in advance.

Hi Denizcan,

some thoughts on your problem:

Did you select internal simulation type?
Does your computational domain cover the complete CAD geometry (small black frame in both figures)?
Is the CAD model completely closed (i.e. watertight)?
Which boundary conditions did you choose?

Regards
Florian
