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 boun...

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
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 60...

Re: AcousticsSolver: Need Help to Set Up a Model
Perhaps I would first check that the boundary numbering of the Elmer mesh files certainly corresponds to the sif file and also check that the test case Thank you very much for your help Mika! I think that that was the reason. I loaded the unv filte into ElmerGUI, saved the resulting project in a ne...

[SOLVED] AcousticsSolver: Need Help to Set Up a Model
Hi guys! So, I am trying to set up a simple model using the AcousticsSolver . As a first step, since I never used the solver, I am trying to use the simplest possible parameters. However, I can only get trivially 0 solutions. Maybe you can help me understand what I am doing wrong. The model is just ...

Re: Output variable for Helmholtz Solver
Hi there! I used the Helmholtz solver a few times and I am slightly confused. In my experience, the results should be pressure wave 1 and pressure wave 2, two scalar fields. Is the pressure wave vector a new feature?
