Which constraint do you like to apply. We may could do a hack, just to get it useble to make this example?

I would just be speed up things a lot if we would only display one arrow per face, but this can not be adjusted ATM.
Lets colour the faces, no 3D-arrows. Mhh...lets say when thre are more than 100 faces to display...

I think a combination whould be good, color to Show which Face belong to the contrain and a Limited number of arrows.

For me, it is the most interesting workbench in FC, very interesting and promising.

hello, I'm trying to add the workbench, when I check the dependencies I have this result:

Code: Select all

Checking dependencies...
Paraview executable paraview not found in path.
when I installed OpenFoam, this install also Paraview. I found the folder of Paraview in /opt.
what should I do? how should I proceed?

edit: please some help.

Sorry - missed this post. The easiest way would be to add a symlink to the paraview executable to one of the bin directories in your path - say /usr/local/bin - with a command like

Code: Select all

ln -s /opt/paraview/bin/paraview /usr/local/bin/paraview

OS: Windows 10
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.17.13541 (Git)
Build type: Release
Branch: releases/FreeCAD-0-17
Hash: 9948ee4f1570df9216862a79705afb367b2c6ffb
Python version: 2.7.14
Qt version: 4.8.7
Coin version: 4.0.0a
OCC version: 7.2.0
Locale: English/UnitedStates (en_US)

I am relatively new to FreeCAD (six months) but can now use it reasonably well after great support from the Forum. I am now looking to move forward into a piece of research (MPhil) and need to use CFD, so CfdOF has been a fantastic start.

I have it all up and running and started with the initial "Elbow" tutorial after going through the Read Me.
CFD Tutorial 1 - Elbow Rev 2.FCStd
(340.26 KiB) Downloaded 7 times
I am also seeing different dialogues to those illustrated in the turorial with failures as indicated by this dialogue:
Elbow Tutorial Mesh Response - Rev P1.PNG
Elbow Tutorial Mesh Response - Rev P1.PNG (23.21 KiB) Viewed 344 times
And others saying:

Response after start of Meshing
0.0: Starting meshing ...
0.1: Exporting mesh region data ...
0.4: Exporting the part surfaces ...
0.5: Running gmsh ...
7.5: ./Allmesh: line 6: [: too many arguments

and

Response from Solver Run (3D Mesh)
0.0: Checking dependencies...
0.0: OpenFOAM case writer is called
0.9: Error writing case:
0.9: [Error 3] The system cannot find the path specified:'c:\\uappdata\\local\\temp\\meshCase\\constant\\triSurface/*.*'
0.9: Write case setup file failed
sers\\user\\

Sorry, very inexperienced in the Forum and don't understand what is going on here. Could you please direct me to some further assistance.

Could you update the workbench and check it again? I ran into the same issue recently and could have sworn I had fixed it. Let me know if that doesn't help.
