Re: SIGSEGV on Arch Linux

Hi, thanks for your inputs. I can confirm that my studies run on the VM, and that is how I will run them for the a while. I will be back to this thread when I look back into this.

Thanks!

Re: Conformal Meshes and Single Physics

Oh! I think I might be onto something. I think that by just exploding the geometry in solids and faces, and then using those to create groups in the mesh, the result is that the surface of the sphere gets "assigned" to the sphere and acts as a boundary for that body only, and not as a boundary to th...

Conformal Meshes and Single Physics

Hi there! I am working on a simple Acoustic problem with the Helmholtz solver. It is a simple room with a sphere source inside. Normally I model the room with FreeCAD, and then I cut out a sphere from its volume. I then export the geometry as step, open up it with Salome, and mesh it. Then I will op...

SIGSEGV on Arch Linux

Hi, I installed Elmer on Arch Linux through this AUR Package . You can see how the software is built by referring to the build() function here . The software builds and install nicely, but it will not run simulations. Every time I try to solve a system, I get this: ELMER SOLVER (v 8.4) STARTED AT: 2...

Modelling Acoustics with Open Source Software: The Series

Hi Guys, I started a series of articles on my blog about modelling Acoustics with Open Source software. My blog is here: https://crocoduckoducks.github.io/. The articles are step-by-step tutorials on how to set up ElmerFEM acoustic problems, although other tools are covered such as FreeCAD, Salome P...

Re: Arch Linux Binary Installer for Salome

Hi! The script above has been broken for a long time. I finally fixed it, and I decided I will try to maintain it. It is now on GitHub: https://github.com/CrocoDuckoDucks/salome-arch-installer By the way, this page was essential to make it work again: https://www.salome-platform.org/forum/forum_9/47...

Re: AcousticsSolver: Need Help to Set Up a Model

Oh I see. Now I understand better the things reported on the Solver manual about bubble functions and stability. I think I can mark this as SOLVED, as the model is now set up :D

Thank you for your support!

Re: AcousticsSolver: Need Help to Set Up a Model

So, I did some experiments and I found that the model seems to work with this sif file only if my meshes are first order: Header CHECK KEYWORDS Warn Mesh DB "." "." Include Path "" Results Directory "results" $ f = 5 10 20 55 100 110 200 220 300 400 440 500 600 700 800 880 900 1000 1100 1150 1200 13...
