Hello everyone
Below, I am attaching a 3D mesh generated from GMSH. However, when I attempt to convert it into a .msh file, it takes a significant amount of time, Please check Is there any mistake in the syntax? Additionally, I am unsure of how to convert a .msh file into a .xml file for a 3d domain. Could you please review the syntax I have written and help me resolve these issues? Thank you in advance.
