Dear all, I'm trying to simulate some layers of a packed bed for a thermal storage tank. In practice i just wanna keep an high element size in the inlet/outlet zones and reduce the element size near the spheres. I built this geometry where two "lines" divide the parts and i tried to structure the mesh far from the spheres. My question is.. can i have a slower variation of the number of elements between the two zones? I think that a strong variation can cause mistakes. Sorry if it's a "strange question" but i'm a beginner here. Thank you

Hey,

Look into options like Transition, Growth rate, Span angle settings. These work with adaptive sizing. I'll include the help links for these.

You can also set biasing to edges along which you can control the bias of element sizes, you can check out the link below for more help on this.
