Re: GMSH macro

Post by CharlieMAC »

I'm having some problems to run this macro. The error is:

Code: Select all

 line 16, in <module>
    import MechanicalAnalysis
<type 'exceptions.ImportError'>: No module named MechanicalAnalysis
How can I solve this issue?

Best,

Hi GMSH macro folks,

encountered a problem I have never realized. It's funny how long it take for some bugs to be found.

- start FreeCAD
- go to Part Workbench
- make a Cube
- start GMSH Macro
- select the Cube in Tree View
- Do not change anything in the GMSH macro
- Run the macro
- Watch out the report window
- the print stops somewhere
- attached is what it prints for me in the report window

Code: Select all

- in the very first line off report the shell command is printed
- for me it looks like

Code: Select all

/usr/bin/gmsh /tmp/tmpo80wMM.step -3 -format unv -o /tmp/Box_Mesh.unv -algo netgen -clmax 5,00 -optimize -order 2
- copy the command
- open a terminal and run the command
- there is much more output printed than in FreeCAD
- see what is printed

I have been trying a few things to get the GMSH Macro in FreeCAD print the whole output and do not stop somewhere, without success. Could you guys confirm this ? Does someone has an idea how this could be solved ?

No one here who can at least confirm the odd behavior off missing gmsh output in FreeCAD?

Just tried to use qprocess instead of subprocess same problem ...

Re: GMSH macro

Post by bernd »

Mhh I'm lost ... It works outside the macro in FreeCADs python konsole ... One have to make sure the step file is still in tmp.

Code: Select all

import subprocess
bin = 'gmsh  /tmp/Box_geometry.step  -3  -format unv  -o /tmp/Box_mesh.unv   -algo netgen    -order 2   -optimize'
output = subprocess.check_output([bin, '-1'], shell=True, stderr=subprocess.STDOUT,)
print output
All output is printed !!

EDIT: Found a file which does not work even if the code is copied into FreeCAD console. Seams it is some FreeCAD related problem. See next post.

Re: GMSH macro

Post by bernd »

I did more investigation but still I could not found the culprit. What I found is inside FreeCAD it just does not print all output. With the file and the code attached this could be repeated. GMSH bin has to be installed and the file needs to be copied to /tmp
part_jacobian.brep
(90.36 KiB) Downloaded 71 times
Code I tested with

Code: Select all

gmshbin = 'gmsh /tmp/part_jacobian.brep -3 -format unv -o /tmp/box.unv -clmax 10 -algo netgen -order 2 -optimize'
import subprocess
print subprocess.check_output([gmshbin, '-1'], shell=True, stderr=subprocess.STDOUT)
If the code is run in a python bash outside FreeCAD I get the following ouput:

So FreeCAD python console is swallowing some text?

I tried to test it, but gmsh dies with *** Error in `gmsh': malloc(): memory corruption: 0x00000000011612a0 ***, so I guess I need to update my system first.

I'm on GMSH 2.8.5 from Debian Jessie repository.

strange. I've never had problems with crashing gmsh neither on debian jessie nor on windows. But you can try other models as well. If the GMSH macro itself is used even for a simple box lots of the output is eaten by FreeCAD. See earlier post viewtopic.php?f=22&t=11182&start=30#p112071.
