Hello everyone,
I'm currently working on a dental framework simulation in ANSYS. I imported my geometry but the mesh quality is very poor, with many distorted elements and warnings about mesh skewness.

I tried fixing it by using a better CAD file with improved design, but I still get the same meshing issues. I also attempted to clean the geometry in SpaceClaim and adjust mesh settings, but the problem persists.

• What file format do you recommend (.step, .x_t, .iges)?

• Are there any geometry repair steps I should apply before meshing?

• Should I use Virtual Topology or Simplify geometry?

Any help would be greatly appreciated!

Is the geometry bad or is the mesh bad? If the geometry is good then you'll will just need to use mesh controls (global and local) to enforce smaller elements at small features. If this is scan data, there are probbably not separet face boundaries. So you really need to use a mesh method set to patch independent terahedrons.

I woud guess, though, that the geometry is bad since it is probably scan data. You will need to take it to SpaceClaim and fit soem skin surfaces or otherwise create better geometry with the mesh data as the guide.
