<div dir="ltr">I have a large command area with irregular topography (
large variation in z values) in which I want to generate mesh. <span class="gmail-im" style="color:rgb(80,0,80)"><br></span>Because the "plane surface" is not plane for this case: the z-coordinates of points on its boundary range from 1 to 90. GMSH 4.3.0 computes the "best" plane surface in the least-square sense, some of the z-coordinates are showing negative z-values.<br><div>Please help me to generate mesh for the cases with large variation in z values ?
