<div>Hi,</div><div> </div><div>I have used Gmsh a lot and have not had the strange problem I have seen recently. This new problem occurs with 3D geometry, where a mesh is finished and appears on the screen, but saving the mesh results in a *.msh file with less than 1 KB in it. In the results *.msh file is only '$Nodes' followed by a 0, and likewise in '$Elements'. I cannot, so far, find any difference in the older files (some 3D) that appear to save just fine. Please let me know if you have seen any problems like this before and whether you know of a solution. </div>
<div> </div><div>I look forward to hearing from you.</div><div> </div><div>Mark Schroeder</div>
