<div dir="ltr">Dear gmsh community,<div><br></div><div style>I would be very glad if someone could answer a few questions. First, my ASSUMPTIONS:</div><div style>- I work with 3D polyhedral geometries</div><div style>- no small features, no small angles (basically pretty simple (nonconvex) geometries)</div>
<div style>- constant mesh size throughout the domain,</div><div style>- first order elements</div><div style><br></div><div style>QUESTIONS:</div><div style>1. When lines are meshed at the beginning, are they always meshed uniformly?</div>
<div style>2. When surfaces are meshed afterwards, can they affect the meshed lines? (I hope not. Does it depend on the meshing algorithm?)</div><div style>3. If I include a boundary mesh (as in <span style="color:rgb(0,0,0);font-family:monospace;font-size:13px;line-height:16.25px">demos/sphere-discrete.geo),</span>can I assume that the 3D mesh does not change (not even by adding a node) on the boundary? Does it depend on the meshing algorithm? </div>
<div style>4. Can optimizing the 3D mesh change the mesh of the boundary?</div><div style><br></div><div style>Thank you very much.</div><div style>Best,</div><div style>Ondrej</div><div style><br></div></div>
