I cannot see what is problem in this project
Guideline to asking for help with a project
Is this supposed to be a CFD analysis? If yes and you want to validate it, please check out the validation page here: https://www.simscale.com/docs/validation-cases/#fluid-dynamics - let us know if that helped and if you need any further questions.
It may be the fact that you have a fixed pressure outlet at non-zero value, try fixed Pa=0…
That is a quick wild guess though as I always use Pa=0 for some forgotten reason
Also I am unfamiliar with purpose Empty 2D BC…
Thanks a lot for you guess,but i did that and the problem still there.Unfortunately.
Do you have another guess?
Did you try getting rid of empty 2D BC as a test?
