Hi everyone,

I've been trying to do vibration analysis but keep running into an error that says:

The following feature has encountered a problem:
-Feature: Compile Equations: Eigenfrequency (sol1/st1)
-Error: Out of memory in mesh processing.

From what I've read it sounds like I have too many mesh elements, which I've tried to reduce by choosing extremely coarse on the Size Settings of the Mesh submenu. What else can I do to reduce the number of elements? Any help at all is greatly appreciated.

If there's a tutorial of something similar online, a link to that tutorial would suffice.

Thanks!!

Hi

there are many discussion on the Forum already, try a search

That said, you can use symmetry, but mostly one need to reduce the number of small details from complex CAD models, such as many fillets, screwholes etc

Good luck

Hi Ivar,

Thank you for your reply. I have been trying to read the forums for some of this info, but I'm fairly new to Comsol, some of the steps (most) seem pretty advanced, is there tutorials of some sort you could point me to so I can learn for myself?

Thanks again.

Hi

check the main site with all the videos and demos, try a few webinars, and go through the model library, print out the pdf and build the models from the text explanations, you will learn quickly
