SUMMARY

The COMSOL Error 6250 indicates issues related to mesh quality or convergence problems during eigenfrequency analysis. In this case, the user, Milena, encountered the error while analyzing a simple square plate made of aluminium alloy 1050. Solutions include reviewing the mesh for quality and ensuring that the solver settings are optimized for convergence. Users are encouraged to consult COMSOL support or community forums for further assistance.

PREREQUISITES
  • Understanding of eigenfrequency analysis in COMSOL Multiphysics
  • Familiarity with mesh generation and quality assessment
  • Knowledge of material properties, specifically aluminium alloy 1050
  • Basic troubleshooting skills for numerical simulation errors
NEXT STEPS
  • Review COMSOL documentation on mesh quality and refinement techniques
  • Learn about convergence criteria and solver settings in COMSOL
  • Explore community forums for similar cases of Error 6250
  • Investigate best practices for eigenfrequency analysis in COMSOL
USEFUL FOR

Engineers and researchers conducting simulations in COMSOL, particularly those focused on eigenfrequency analysis and troubleshooting numerical errors.

Hi all,

I'm trying to run an eigenfrequency analysis on COMSOL. I have the geometry (a simple square plate fixed in one side), the material (aluminium alloy 1050) and the mesh.

However, when I run the solver, I find the famous error 6250. What, exactly does that mean?

Thanks in advance,

Milena

You can ask to Comsol for the problem or upload the file for review.
Usually are problem with the mesh or problem of "no convergencia" of the solutions
 
You should do a search for you error on Google, it comes up with many threads on the subject.

Thread 'Hydraulic Cylinder Held In Place Until Needed'

I have encountered a vertically oriented hydraulic cylinder that is designed to actuate and slice heavy cabling into sections with a blade. The cylinder is quite small (around 1.5 inches in diameter) and has an equally small stroke. The cylinder is single acting (i.e. it is pressurized from the bottom, and vented to atmosphere with a spring return, roughly 200lbs of force on the spring). The system operates at roughly 2500 psi. Interestingly, the cylinder has a pin that passes through its...
