Sorry in advance for the long post It looks like most websites don't take into account the effective length for the port. not always an issue but with the choices you made for the port dimensions it is. the effective length is equal to the port l…

I agree with victor, I looked at your model and did hand calc for a Helmholtz resonator. V=.000512m^3 l=.01m d= .02 m c=345m/s ln=l+1.6*d/2 (this is for the effective length) A= area of openting f=c/(2*pi)*sqrt(A/(V*ln)) this gives a resonant …

I am a big fan of Fusion 360. It is free for anyone making under $100,000. in addition to being good CAD the CAM capabilities are great. It is web based which I was not a big fan of but is ok. you can work offline but I usually don't Main Featu…

I used your suggestion to switch over to Static 3D and I can now run the model. I am still having issues getting results but I am getting closer. Thanks for the help.

Thanks for the help I made this model but I am having trouble getting it to work. I can solve the model with calculix but I am having trouble adding the custom step. I add the step but it does not seem to show up in the .inp file. any ideas wher…

Thanks for the triad tip that helps a lot for screen shots. Regarding edge refinement. I like to manually control how many elements around a hole or some other feature? Thanks Timm

I have a couple suggestions. add the other orthogonal views xz, yx, etc this one might be more difficult. on the imported cad define certain edges to have a set number of nodes before meshing. I attached a picture
