Re: Visible waves generated by Helmholts Equation.
A couple of corrections. The driver bc's should be changed to pressure wave1 = 10 and pressure wave2 = 0. The fluxes should be left blank. Attached is a new .brep file than is a complete slice of the horn. The half slice seemed to be introducing some artifacts. The new file also increases the air vo...

Re: Cannot use "Scripts" module which has not yet been found.
Found the problem. I apparently -somehow- added an "s" to the end of Script in the CMakeLists.txt file. Dumb move.

Cannot use "Scripts" module which has not yet been found. (Void)
I decided to get rid of my virtual machine and build a copy of Elmer on my Debian 11 machine.

Visible waves generated by Helmholts Equation.
When I started to model a hyperbolic acoustic horn assembly, I wanted to illustrate the expanding wave fronts. My goal was to determine how much directionality would be introduced at higher acoustic frequencies. I had trouble finding examples that did this. Most Helmholtz analyses showed a general e...

Re: ElmerGrid output garbage
I finally got the bugs out of the problem and plan on including it in contributed cases. I'm also including a .png file of the run of a 5Khz problem. I hope this helps other people.

Re: Generating visible waves from an acoustic waveguide
Well I finally got back to the project and got results. Though not quit the results I wanted. The horn seems to have some directionality at higher frequency. I will add the cif file and a screen shot as soon as I find out why I can't load attachments. I'm going to try setting up the same problem wit...
