[ANSYS Meshing] How to combine two cells?

xuegy · March 5, 2018, 17:18

Hello all,

I have encountered a strange problem.

I used CutCell to generate this mesh. ANSYS split the boundary cell into 1 and 2, which should be a prism like 3. I need the boundary face to be periodic, so this strange split is not acceptable. I searched online. It says that only non-cutcell mesh can apply match control. Seems like the only way is to manipulate the mesh manually? Is their any tool to fix the mesh?

Thanks.

You are correct; CutCell meshing in ANSYS can occasionally result in unforeseen divisions in boundary cells, which can lead to complications when defining periodic faces.basketball stars

That's really inconvenient when meshing in CutCell. I don't know any other way but to re-divide the mesh myself.
