2D/3D optimized mesh

Using SimScale CAD & Meshing
1

Good evening,
I am working on creating a good mesh for a full factorial optimization of a Fowler flap for a university project (I have an academic account). My professor suggested creating a single-cell-width domain since SimScale and OpenFOAM don’t support a 2D mesh. Because I need to run numerous simulations, I’d like to generate a mesh with as few cells as possible and conduct a mesh independency validation.

Unfortunately, I can’t control the cell size, and when I reduce the width of the domain, the cells get smaller and smaller. How can I manage this? The project has already been shared with support.

Hi @sraggi, thanks for posting on the forum and welcome to the SimScale Community :handshake:

I guess the best workflow to run these sorts of analysis would be something like this:

  1. Generate a mesh using SimScale with no concern with the number of elements along the thickness
  2. Export this mesh to ParaView so that we can export the mesh elements from a single surface
  3. With this surface mesh, extrude the mesh in OpenFoam for a single element thickness
  4. Import the mesh in SimScale
  5. Use an Empty2D Boundary condition for the analysis.

My colleague Ricardo has a great tutorial on how to do this here.

The dictionary he mentions is here.

Cheers
