GMSH macro

[psicofil]

I create a new thread for this macro which started to discuss here viewtopic.php?f=18&t=10066 and here viewtopic.php?f=18&t=10732&start=20

I've updated the macro adding support for 1D and 2D meshes, which can now be viewed on FreeCAD from version 0.16.5030.

I tried the macro on Windows and got the following error:

Code: Select all

Running: C:/Users/ubrammer/gmsh-2.8.3-Windows/gmsh.exe c:\users\ubrammer\appdata\local\temp\tmpspflzn.step -3 -format unv -o /tmp/Part__Feature_Mesh.unv -algo netgen -clmax 5,00   -optimize -order 2
Unexpected error in GMSHMesh macro: <type 'exceptions.WindowsError'>

There seems to be a problem with the path to the temporary step file. This path should not contain backslashes.

I would delete this line 34
self.title = QtGui.QLabel("<b> Macro GMSH mesh generator <b>", self)

and add instead at the end of the file
d.setWindowTitle(" GMSH mesh generator")

so the header is always visible as dock title

I have added your macro collection (the complete git) to the pluginloader.
I'm still looking for nice icons for your macros

I can't get the macro running.
every time i get some errors

Code: Select all

Unexpected error in GMSHMesh macro: <class 'subprocess.CalledProcessError'>

i had to change my bin gmsh location to

Code: Select all

gmsh_bin = "/Applications/Gmsh/Gmsh.app/Contents/MacOS" #"/usr/bin/gmsh"

I created something what looks like the test obj in the youtube movie. to try a bit on but i've tested other files also but they don't work eighter.
Do i something wrong or is it Mac(version?)

In order to get the macro working under Windows, I had to change the arguments for the subprocress call. The arguments have to be elements of a list without any spaces in it.
I have this week no access to the computer, where I did the changes. I will post my version next week.

Hello Jee-Bee. Sorry for the late response.
Try the new version: https://github.com/psicofil/Macros_FreeCAD

i had to change my bin gmsh location to gmsh_bin = "/Applications/Gmsh/Gmsh.app/Contents/MacOS" #"/usr/bin/gmsh"

You have to put the full command gmsh, in your case I think it would:

Code: Select all

gmsh_bin = "/Applications/Gmsh.app/Contents/MacOS/gmsh"

Any error or if it works please wrote in this post. I do not have a Mac to test the macro.

I'm working for the macro to work in windows, the problem I have now is to import the resulting mesh because the tempfile.tempdir command returns the address of the temporary file of the form \temporalyFolder\ .... and when trying to open with Fem.insert throws an error, but if I change "\" with "/" the mesh is imported without problem. Tomorrow I will try to solve that problem. The problem of space in the command think are already solved.

Already corrected it in the new version of the macro. Thanks.

As announced, I post my version of the GMSH macro, working under Windows. Sorry for not making a pull request to the githup repo, I do not have the time to perform all the steps at the moment.
The macro works for me under Windows. I did not include the additional GMSH options in the call. This is still to do.
I have changed, how the temporary directory is used.
I changed the arguments for the subprocess call.

The attached file is a real zip. Please unzip it.
