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 &#8220;lines&#8221; 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&#8217;s a &#8220;strange question&#8221; but i&#8217;m a beginner here.
