<div dir="ltr"><div><div><div><div>Hi <br><br></div>My mesh definition includes topography, which is inputted into geo file as a number of Ruled Surfaces that are combined into a Compound Surface.<br></div>When I do 2d mesh, gmsh first meshes all the small ruled surfaces and their boundaries and then meses the compound surface.<br>
</div>It seems as a waste of computational time as the Ruled Surfaces are not needed to be meshed. How to tell gmsh not to mesh them?<br><br></div><div>Thanks for help!<br></div><div><br></div>Cheers<br>Michal Kordy<br></div>
