Hi,

Im trying to model mesh geometries with varying step size. (Top plate, Beam, Step - between beam and top plate). I have ok mesh for 0.5 step size. But while decreasing the step size from 0.5mm to 0.025mm, bad quality cells around the O-grid are created. Is there anything I could do to avoid them? I read some of the threads here (edge alignment and another O-grid, varying node size etc) but I think in my case the bad cells are created by decreasing of the gap between the two parts.

Thank you.
