<div dir="ltr"><div>Hello,</div><div><br></div>Has anyone submitted a bug regarding the C3D20 export problem in Gmsh? (I am cc'ing the <a href="mailto:gmsh@geuz.org">gmsh@geuz.org</a> in case no one has.)<div><br></div>
<div>It would be an easy fix if someone wanted to set up a build environment for Gmsh. The nodes are not ordered incorrectly. Looking at th 2.8.2 source, line 245 of the header file Geo/MHexahedron.h needs to reorder the local node numbers. There are examples in the lines above and below. The local node coordinates are in the Gmsh and CCX docs. Double check it, but this should be correct (these are the comments from my translator):<div>

<br>
For example, You have 1.INP file you want to convert.<br>
<br>

<br>
2. There are copying my program KONVERTOR.EXE (take KONVERTOR.EXE from archive, from directory DEVCPP)<br>
<br>

<br>
3. Windows menu click: "START" - "RUN" - "CMD", press ENTER key<br>

<br>
press ENTER key<br>
