Pipe flow / Internal fluid dynamics with SnappyHexMesh
I like to apply SnappyHexMesh to a pipe-like flow, respectively to internal fluid dynamics. I read the manual and struggle with the following statement:
"The objective is to mesh a rectangular shaped region (shaded grey in the figure) surrounding an object described by and STL surface, e.g. typical for an external aerodynamics simulation."
Isn't it possible to apply SnappyHexMesh to internal flow? Does anybody have experience with this topic?
It certainly is possible to mesh interior regions, it is just that the instructions are written with only a single application in mind. It all depends on where you put the internal point in the dictionary file.
have you run your case?
I'm able to run external aerodynamics simulation, but I don't understand yet how to run internal simulations.
I think, like Gecko wrote, I have to put right internal point in the dictionary file, but I don't understand how.
Thank you in advance for your help.
for mesh the internal region of your .stl geometry you just have to change the coordinates of the LocationInMesh point in the sHMDict file
Let me know if it worked
