Re: parametric sweep

Hi Peter, This sounds like it's exactly what I want, I cannot find much in the latest solver or models manual which describes how to use it, would you have a minimal example sif file so I can see how it is used? Regards Mark Hi. If you are still struggling, I think I solved the problem. Have a look .

Scanning with parametrized keywords (parameter sweep)

Hi there! I wanted to share on the forums a simple way to do scanning simulations (kinda like COMSOL parameter sweeps). I have two reasons for doing that: People have been helping me, so I wanted to "balance the karma" sharing a solution for a problem which I hope will help someone else. T...

Re: Eigenmodes of a Room

Uhm... feels like there aren't simple ways to solve this. I guess I will have to look into writing my own solver. Pretty weird that Helmholtz equation does not support eigen analysis. It is one of the most interesting things in acoustics... If I manage to get something working I will consider sendin...

Re: Vtu export fails

Thanks! Still have to double check, but this seems to do the job: Header CHECK KEYWORDS Warn Mesh DB "." "." Include Path "" Results Directory "" ! Simulation Parameters: ! Frequency [Hz]: $ f = 3583 ! Velocity [m / s] $ v = 0.000001 ! Reference Pressure [Pa]:...

Re: Vtu export fails

Hi In Solver 1 set Exported Variable 1 = PressdB Nonlinear Update Exported Variables = Logical True And maintain the PresdB in the BF section. I would not use the underscore in the variablename. -Peter Hi Peter, thank you very much. I indeed tried it and seemed to be working just fine. Here the sif...

Re: Vtu export fails

Hi, what happens if you disable the Resultoutput Solver and change the extension from .ep to .vtu in the Simulation section? HTH, Matthias Hi Matthias, thank you very much. That seems to be working as well, I would say. I actually like it much more (it feels simpler). Thanks Again. Now I only have ...

[SOLVED] Vtu export fails

Hi guys, hope I can get some support here. So, I am running a simple acoustic simulation with the Helmholtz solver. Here my sif file: Header CHECK KEYWORDS Warn Mesh DB "." "." Include Path "" Results Directory "" ! Simulation Parameters: ! Frequency [Hz]: $ f...

Eigenmodes of a Room

Hi there cool people! I managed to have Elmer running on Mac. My goal is to run acoustic related multiphysics simulations. At the moment I have been just playing with Elmer as I am completely new to it. I already been able to find modes of elastic objects (like rods of metal and similar). However, I...
