Tips or tricks on mesh smoothing and quality improvement
Thanks in advance for this wonderful package! Gmsh really provides powerful programmability and automation capabilities, which is exactly what I need.
I'm simulating fluids going around obstacles. My problem is that when I do batch simulations, some cases inevitably have too big residuals(e.g. velocity more than 10-4), which I think is a mesh quality issue. I was wondering if there is any way to significantly improve the mesh quality.
Below I have provided two images, first one is the gambit processed mesh and the second is the Gmsh mesh, I think first one is clearly better for smoothing, and it did provide less residuals.
