hfcMYSTRAN - a test case

[johnwang]

Code: Select all

14:02:03  Running the Python command 'hfcMystranNeuInWire' failed:
Traceback (most recent call last):
  File "/home/hugo/.FreeCAD/Mod/hfcMystran/hfcMystranNeuInWire.py", line 203, in Activated
    iniFout = open(inifileOut,"w")

[Errno 2] Datei oder Verzeichnis nicht gefunden: '/usr/local/Mod/hfcMystran/hfcMystran.ini'

I use:

Code: Select all

ininame="Mod/hfcMystran/hfcMystran.ini"
        inifile = FreeCAD.getHomePath()+ininame

Under Windows 10, FreeCAD.getHomePath() is where your installed FreeCAD. So hfcMystran.ini is in the same folder as all the PY files.

You installed the WB at "/home/hugo/.FreeCAD/Mod/hfcMystran/hfcMystranNeuInWire.py", the WB expects hfcMystran.ini at "/home/hugo/.FreeCAD/Mod/hfcMystran/hfcMystran/hfcMystran.ini'.
Don't know why FreeCAD.getHomePath() is pointing to '/usr/local/'.
Even so, you put hfcMystran.ini at '/usr/local/Mod/hfcMystran/hfcMystran.ini', it should be found.

The content of hfcMystran.ini could be one line text like:

Code: Select all

/usr/local/Mod/hfcMystran/

Not sure if you need the end '/'. No Linux, can't test.

If my PR is merged it works out of the box even if mystran is not installed at all. No ini is needed. Just your module, open file and the result will be read into FreeCAD.

Thanks for mergin... New issues around... See https://github.com/ceanwang/hfcMystran/issues/2

Merged, but when open NEU, it still says not supported. Windows.

[bernd]

you only merged the changes in NEU reader but not the Init.py file I added. My branch is deleted already. I am on the way, I will post it if I am on a computer.

[bernd]

ohh no my fault ... I forgot to include it ...

[bernd]

attached the init file for your hfcMYSTRAN workbench to directly load NEU files. It is just one line of code.

Code: Select all

FreeCAD.addImportType("FEM result Mystran displacements (*.NEU)", "hfcMystranNeuIn")

Init.py

Thanks, Worked. Just the file extension is 'bdf'. I prefer 'dat', because Mystran testcases are mostly 'dat'.

In you screenshot, there is a ResultPipeLine. Is that you created after open the file?

A test case using CBAR pin flag as hinge
from http://www.iberisa.com/soporte/femap/cbar.htm
Solved with Mystran.

yes. manually created vtk resultpipeline and deformed with some factor.
