CfdOF with Appimage

[sulf]

Hello,

on the Xubuntu 20.04 there is an qt5.15 incompatibility. Therefore I have to use the Appimage, which is working fine.

But how does one install the dependencies of the cfdOF workbench?

thanks

There are instructions on installing dependencies on Linux in the README here: https://github.com/jaheyns/CfdOF/blob/m ... md#linux-1. You may need to go to the CfdOF preferences page to input the dependency install directory if it doesn't register on its own.

still using the appimage:

cfdOf dependency check seems fine, even if gmsh folder is not defined.
And installing cfMesh from locally zip file takes hours: Busy - please wait...

my guess is, that installing appimage cfdOf workbench is not the same as with the repository version.

After a while, I ran the dep check again and got confirmed that all deps were installed.
Clicking the okay button triggered segmentation fault:

Can someone check, if appimage version of cfdOf is working as supposed, please?

[justwanttoknow]

Works on my machine using FreeCAD_0.19.3-Linux-Conda_glibc2.12-x86_64.AppImage on Ubuntu 20.04.
Just paraview cannot be started directly from FreeCAD.
So there is hope

Hi,
I use also the FC AppImage and CfdOF WB works.
It's a bit "tricky" to get all dependencies, for that here my workflow for it :

Needed steps to get CfdOF WB working (OpenSuse Tumbleweed)

This pakages have to be installed ( status 10.01.2022 ) :

Gmsh
zlib-devel
openfoam2106
openmpi1 ( only openmpi1 contends one needed pakage )
python3-vtk-openmpi1 ( i install it, but i’m not sure if realy needed )

With OpenFoam and OpenMPI OpenSuse installs a Selector which needs to be configured.
For the type this comands at a terminal ( no root permission needed )

cnf openfoam2106
mpi-selector --set openmpi1


At /etc/profile.d a file named custom.sh with the contend

PATH=$PATH:/usr/lib64/mpi/gcc/openmpi/bin
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64/mpi/gcc/openmpi1/lib64/

must be put in. ( root permission needed )

Restart the computer !


If this is done, it’s possible to install cfMesh and Hisa

Both need a few minutes.
And don’t mind about the errors shown during installatin. It seams that it don’t matter...

Of course you have to adapt the pathes to the location where openmpi is installed...

Thank you HerbK,
I recently found out the settings of openmpi and openfoam, but the custom.sh was new for me. It helps

thanks

Just paraview cannot be started directly from FreeCAD.

There shouldn't be a problem starting Paraview form the Appimage any more. Could you let me know which version of Paraview you are using?

Clicking the okay button triggered segmentation fault:

I'm not sure what's going on here, but there shouldn't be any issue running from the Appimage. Are these issues reliably repeatable? Please provide your FreeCAD version information.

[sulf]

well, version 0.19.3 appimage works, while weekly build 0.20 is missing matplotlib and therefore may cannot import Plot wb.

Its fine for me to use appimage version 0.19.3 now.

Official repo version is not working on my *buntu system because of qt5.15 requierment.

Just paraview cannot be started directly from FreeCAD.

Sorry Oliver, I've completely missed this notification!

Paraview 5.7.0
error message is "ModuleNotFoundError: No module named 'paraview'"

no ParaView executable path given in CfdOF-preferences (where can this be found in Ubuntu?)
Possibly it is a messup with various OpenFOAM installations. I also had a segfault, when starting paraview from terminal, So don't spend work on it unless you have a solution right away.
