I created a new simulation project called ' EarPhone 1 ': Check wind noise More of my public projects can be found here .

Hi there, thank you for using the forum! Make sure to add the troubleshooting threads to the “Project Support” section. The description of each category can be found here: Categories - SimScale CAE Forum Regarding the project, I have a few comments: *In order for the compressible analysis to work…

[image] Today I retry to upload our earphone product to do simulation, but suck in following status. Please help to advise how to solve it to achieve simulation? Or are you able to access my page to help ? Our design is a ear phone which for bicycle rider use. It is fix on helmet belt, place in f…

[image] 11:06 am I follow you afdvise to make the 6 body into 1 body, and set the slip wall, to redo the simulation. But it still have error aas above. Please help me to correct. The project in follow link. https://www.simscale.com/workbench/?pid=8616269697522253978&mi=run%3A7%2Csimulation%3A4&mt…

The Mach number is the speed of the case divided by the speed of sound. If this number is larger than 0.3, then the compressible analysis is the correct option :slight_smile: Best regards, Fillia

[image] I follow your previous advise to change it to 'imcompressible ’ to run Earphone 1 again. error message as this. https://www.simscale.com/workbench/?pid=150839808297911894&mi=spec%3A1f6aee32-7cb4-4e10-962a-cb050c76238c%2Cservice%3ASIMULATION%2Cstrategy%3A23&ps=analysis%2FboundaryConditio…
