Re: Build on Windows
Build through WSL is not really native windows build. i found the below issues which mentioend a script of windows build under MSYS2+Mingw64: https://github.com/ElmerCSC/elmerfem/issues/200 But it seems now the link is not longer in use, does anyone have this script? From a different post "Hi, ...

Re: Non-reflecting boundary (helmholtz solver)
Is there any plan to implement PML? This seems to be a very useful feature. Hi PML has not been implemented. However, Cwang proposes some techniques that might not be too hard to implement and might even work without coding. It would of course require definition of a buffer zone, maybe computation o...

Re: Complicate Noise Source Input in Acoustic Analysis
Hi Peter, The node ID maybe a bit difficult, since they may be generated with different node naming sequencies. I call the file data through an independant function, the function input is X, Y, Z coordinate and output is coordinate pressure value. This function will be called directly from the user ...

Re: Complicate Noise Source Input in Acoustic Analysis
Thanks to your kind help, i wrote the attached example user functions and try to assign different acoustic pressure loads to node points. I am sorry but i have below additional questions: 1. It seems body force user functions is relatively simple, but i assume body forces can only be applied to a bo...

Re: Complicate Noise Source Input in Acoustic Analysis
I noted in the models manual it mentioned the use of pressure body forces is rather seldom, is there any differences between body forces or boundary conditions? In previous simulations, i just used boundary conditions such as wave flux or pressure etc? I now already have noirse source in terms of dB...

Re: Complicate Noise Source Input in Acoustic Analysis
Many thanks for the kind help, Peter. By meaning UDF, do you mean that writing a .f90 file and compile it as an solver? Or just write some functions within the .sif file? What i am trying to do is to assign differnt pressure wave values on differnts nodes. Very sorry that I am a starter of UDF and i...

Re: Complicate Noise Source Input in Acoustic Analysis
Hi Peter, many thanks for the kind response! I am thinking to associate the source item with discrete nodes. Do you have any kind suggestions on how this can be done? Hi Yes, the Helmholtz solver looks for source terms named "Pressure Source 1" and "... 2" in Body Force section. ...

Complicate Noise Source Input in Acoustic Analysis
Is that possible to include relevant complicate noise sources in acoustic analysises in Elemer? For example, noise sources calculated from pressure field or monopole source / Dipole source / Quadrupole source?
Is there any examples on this?

Re: Structure Analysis with both Beam and Shell elments
Mika, if you don't mind, i have another question regarding shell/beam coupled solvers: does our beam solver support asymmetric beam properties? As you may understand, beam with asymmetric properties is quite common. Thanks for testing, As an update I mention that partially nonlinear analysis can now...
