Hi Guys,


i get a solver error that i don´t understand.




Does anyone knows the reason for this error? I think it is a Problem with a function...

I solve a multiphase Problem. Perhaps it is the Water volume fraction scipt.



The script is:


if (z<0.0):value=1


The script describes that everything under the z-Level "0" should be water. But i can´t see any mistake here...

(Z-Level=0 is in the middle of the geometry)




Thank you very much!

Hallo ydigit,


thank you for your reply. You are rigth it wasn´t the script.

I have found the problem, it was the mesh. I had to much bad elements inside.



What are your settings under "check Elements" for CFD Surface meshing?


Could you tell me what points i should consider for CFD-meshing?

Generally I try to avoid elements with small angles <10°. Also check for any really small elements (cannot give an absolute value though). 


Say you average element size is ~10, then search for elements <1 to see which are smallest (sliver) elements. These are typically going to create big trouble for boundary layer meshing. 

In a way both are related issues. Small angles lead to small elements.
