<html><body><div style="color:#000; background-color:#fff; font-family:times new roman, new york, times, serif;font-size:12pt"><div>Hello forum,</div><div><br></div><div>After creating a .geo code with no physical groups, I am able to create a mesh for the model of surfaces surrounding a tube. However, after inserting two physical groups of points and using 2D meshing, the .msh file displays only the grouped points. The surface mesh is gone! Is there any way to create a 2D mesh which includes both the ungrouped surfaces and grouped points into one .msh file? I require for it to be in one .msh file, since I plan on running stress/strain simulations using Code_Aster.</div><div><br></div><div>Thank you.</div></div></body></html>
