> I am generating a 3D hexahedral mesh for a cylinder by extending a circle with extrude command. The mesh is created in the right way but the mesh file writes the center of circle(in my case (0,0,0)) and its extruded vertex (0,0,5) in the nodes list. <br>

> Is there any way to remove these center points from the .msh file or to make them the part of mesh?</p>
<p dir="ltr">To have them omitted from the output, declare some 'physical entities', then Gmsh saves only those; e.g. a Physical Volume for the cylinder and perhaps some Physical Surfaces (which might also be useful in your finite element analysis for imposing boundary conditions).</p>
