Installation problems of depencendies for CfdOf on Linux with AppImage

[tectone]

Hello,

I want to use Cfd or CfdOf to run a couple of simulations of flow in a pipe. But I am struggling with the installation of the plugin. I am running Freecad as the AppImage version on Xubuntu:

OS: Ubuntu 19.04 (XFCE/xubuntu)
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.19.22960 (Git) AppImage
Build type: Release

Python version: 3.8.6
Qt version: 5.12.5
Coin version: 4.0.0
OCC version: 7.4.0

Ubuntu:
LSB Version: core-10.2019031300ubuntu1-noarch:printing-10.2019031300ubuntu1-noarch:security-10.2019031300ubuntu1-noarch
Distributor ID: Ubuntu
Description: Ubuntu 19.04
Release: 19.04
Codename: disco

I followed the steps of the Cfdof manual:
1. Downloaded the Appimage
2. Installed the Plot workbench
3. Installed Cfod

When I do the dependency check, this the output:

Gmsh is installed via the package manager and I can also start the GUI of the Programm

Code: Select all

user@host:~$ gmsh --version
4.7.1

I installed hisa and cfmesh from the properties window of the cfdof window. Further I installed PyFoam (with Pip3), python3-matplotlib and paraview.

Openfoam install directory: /home/user/OpenFOAM/user-7
ParaView executable path: /usr/bin
Default output directory: /tmp

How can I fix the "gmsh is not installed" error?

Thanks for your help!

I want to reproduce this tutorial with a different system in particular:

But as you can see in the screenshot, after clicking create mesh, there is no mesh being created afterwards....
I also attach you the compiling logs of HISA and cfmesh. Maybe there is a clue to fix the problem.

Mod edit: moved to CFDoF subforum

I was able to create the mesh with snappyHexmash (the way you are supposed to click is a little bit contraintutive for me). But gmsh I still not recognized by the Plugin...Any hints?

Should be fixed...please update your workbench.

Your OpenFOAM directory should be set to /opt/openfoam7, not your user directory.

Yes, my fault. But the gmsh error is persistent, even after updating the workbench.

It looks like your system is missing the g++ compiler.
