Hello.

I am using blender 4.2 and vi-suite07-master.zip.
I stopped using Ubuntu and installed and started using Manjaro, an ArchLinux derivative.

Here is what I installed
$ sudo pacman -S blender
I installed Blender 4.2.
$ yay -S pyqt6
$ yay -S python-kivy
$ yay -S python-matplotlib

I installed what is described in the manual as I run the koji_envi_test.blend file you gave me, but when I try to create a graph, it says “Matplotlib cannot be found by the python instration used by Blender” and the graph is not displayed. What should I do? Please advise.

I have netgen as follows

git clone https://aur.archlinux.org/netgen-git.git and makepkg.

(P.S.)
I am not sure how to install openFOAM10.

Regards.

Hi.

Here is the section from the new user manual version I'm working on.

I suspect your problem is that you are trying to use pyqt6 and not pyside6.

Arch has a nice package management system called pacman, and most packages required can be installed via pacman. The packages required are:

blender
pyside6
python-matplotlib
python-kivy

All these can be installed with the sudo pacman -S package_name terminal command.

In addition, netgen-git and openfoam-org need to be installed from the Arch User Repository (AUR) https://aur.archlinux.org/. The PKGBUILD file for netgen-git can be downloaded from https://aur.archlinux.org/cgit/aur.git/snapshot/netgen-git.tar.gz, and openfoam-org from https://aur.archlinux.org/cgit/aur.git/snapshot/openfoam.tar.gz. The folders within these archives should be decompressed to your file system. Navigate to each created folder with the terminal and run makepkg -fsri to build and install them.

There are also helper applications to automate the installation of AUR packages; I use pikaur https://github.com/actionless/pikaur.

Thank you for your prompt reply.

I am still very new to ArchLinux, so I will take my time. I would like to show VI-Suite on Windows 11 to my fellow researchers at this year's AIJ conference. Next year I would like to present a paper in VI-Suite. I will report back if there is anything else I can do.
