Elmer Discussion Forum

The main subject of this post is to clarify the practical implementation of the Flux Solver in acoustics (might be relevant in other physics as well). My attempt to compile the latest Elmer source code on Linux Mint 17 64bit did not succeed (based on the error messages, it looks like there are bugs ...

This is the continuation of my previous two posts on this thread: http://elmerfem.org/forum/viewtopic.php?f=2&t=4918 It is continued here because this subject is not directly related to Launchpad, but rather to the direct compilation of the source code. The objective is to demystify the building...

Here is one more very important point to consider. In the ElmerSolverManual.pdf it is stated: Elmer may be also compiled with Mumps, SuperLU, and Pardiso. The licensing scheme of these software do not allow the distribution of precompiled binaries but everybody may themselves compile a version that ...

Hi Anil, I am having the same problem; trying to install the latest Elmer version on Linux Mint 17 cinnamon with no success so far. Tried to install the version for Ubuntu 16: https://launchpad.net/~elmer-csc-ubuntu/+archive/ubuntu/elmer-csc-ppa/+build/13884688 but it did not work. There are at leas...

Hi Matthias and Anil, Thank you for your comments and suggestions. I am working on the compilation of the latest version of Elmer on Linux Mint 17, which will take some time, because I will have to reorganize my hard drive first to make space for an extra partition. The reason for me using the older...

...continued from above: And here is how it looks like: tube_SPL.png I am looking forward to hear your feedback about this analysis, whether it is correct or there are any mistakes to be corrected. It would be great if somebody could explain (and show) how to generate at least the velocity field (bu...

...continued from above: Here is an image of the real radiation intensity field (x component): tube_Re_Irms.png The sound power that passes through the input boundary can be calculated in two ways: a) From the pipeline node Re(I) create a plane slice at origin: 0.000001, 0, 0 (when x=0 selected, got...

...continued from above: Here is the gradient calculated by Paraview: tube_Paraview_Gradient_p2.png This forces us to generate the velocity field using ElmerSolver, which is actually the best way to do it even if the Paraview filter gets fixed. The best would be to calculate the velocity as flux dir...

The “Simple Pipe Acoustics” project posted by JoeD motivated me to try using Elmer for acoustic simulations. I have never used Elemer before, so please be patient with me. It would be really great if we could create a collection of sorely needed acoustics tutorials that drill down to the nitty-gritt...
