<div dir="ltr"><div><div><div><div><div><div><div><div>Dear Sirs,<br><br></div>I am writing you because I have a problem trying to make FreeCAD (opensource software for CAD drawing <a href="http://www.freecadweb.org/">http://www.freecadweb.org/</a> ) and GMSH working together. More specifically, my idea is to create a surface in FreeCAD, save it as *.stl and then open it in GMSH to have the volumetric mesh.<br>
<br></div>Well, so far it has not work and I wonder if any of you have had the same problem. The steps I am doing are this ones:<br><br></div>- Create the surface in FreeCAD and save it as *.stl; as example I have created a cylindrical surface in FreeCAD and attached it to the email. The *.stl is saved in binary format from FreeCAD and i have noted that the resolution is really poor.<br>
<br></div> - Given the poor resolution, I would like to remesh the stl file in gmsh before creating the volumetric mesh. To do this, I have followed the tutorial about stl remeshing. I attach to the email the *.geo script I used to remesh.<br>
<br></div>The problem is that the stl file is not remeshed at all. Any help? Another question: has anybody imported CAD draws in GMSH? If yes, with which software were they created?<br><br></div>Many thanks for the help,<br>
<br></div>Regards,<br><br></div>Paolo Tricerri<br></div>
