[Other] Installing OpenFOAM 7 & 1912 & ExtendedFOAM

EternalSeekerX · April 27, 2020, 20:15

Hello everyone!

I hope everyone is staying safe during this time.

I am a CFD beginner and my only proper CFD experience was using Ansys 15 CFX and Fluent simulating 1000+ iterations of turbulent flare plate using K-epsilon, K-omega and SST solvers to validate a NASA case. I wanted to go more deeper into CFD and I have found out there are many interesting and exclusive tutorials, example cases and validation cases for many opensource and closed source programs.

I know Ansys Fluent and Star-CCM are free for students and will work on windows, as well there is only one version of Su2 code. However I found out there are 3 different variation of OpenFOAM.

I have read this old thread: OpenFOAM.com versus OpenFOAM.org: Which version to use?

I want to install and then test and run tutorials for each variations.

I have access to Ubuntu 20.10 through WSL and I also have access to Pop!OS and Manjaro in a VM for x86. Interestingly I want to also attempt to run it on an arm64/aarch64 version of Ubuntu 19.10 inside a proot container.

I understand that I can use alias in the .bashrc file to differentiate each versions.

Now I have a few questions:

1). The build instructions for each version shouldn't differ if I am running in WSL or VM correct?

2). I have read this website: https://gitlab.com/arm-hpc/packages/...kages/openfoam and It seems specifically for arm64 I can only install OF5 or OF1912. However is it possible I can build all three versions (are the files architecture agnostic) or is there a specific flag I need? Has anyone build OF for arm64?

3). Fortunately the OS I use have the latest or 2nd latest version of Paraview, can I use it or would i need to build paraview again? If i could use it, do I just skip the paraview portion of the build guide?

Anyway thanks for your patience, looking forward to hearing back.

each version has a quite clear guide for installation, and they may differ, though slightly.

please follow the links below - and install them separately by referring each guide.

wish you the best.
