How to Troubleshoot Error 6262 in Laser Simulation Using COMSOL?

[Tom_Hugill]

Hey I am trying to create a comsol model to simulate laser forming using comsol. As a starting point I am using the heating with a moving laser tutorial and adapting from there.

The first stage is to model the beam modes. I the tutorial the beam is treated as being infitesimally thin and is modeled using a 1D geomerty line the same length as material thinkness.

Ive tried to model the laser using 3D geomerty as a cylinder and then used the beam intensity equations through the thickness to simulated the beam thickness. However I keep getting "ror: 6262
Extrusion coupling operator interpolation failed for at least one point: no source point found
- Geometry: 3
- Subdomain: 1
- Destination coordinates: [0.0015; 0.04; 0.00108145932313381], [0.0015; 0.04; 0.001065850060828009], [0.0015; 0.04; 0.001080691388131417], [0.0015; 0.04; 0.001064698498982615], [0.0015; 0.04; 0.001080525626045624], ...
Failed to evaluate variable Jacobian.
- Variable: T" When I try and solve the model.

The next stage would be to implement the intensity profile of the various beam modes over the thickness of the beam.

If anyone has any ideas or can help me solve this error please let me know

.Hello,

Thank you for sharing your progress on creating a COMSOL model for laser forming. It sounds like you have made some good progress in adapting the heating with a moving laser tutorial for your specific application.

Regarding the error you are encountering, it seems like there may be an issue with the geometry or the settings for the beam intensity equations. I would recommend double-checking the geometry to make sure it is accurately representing the cylinder shape of the laser. Additionally, you may want to check the settings for the beam intensity equations to ensure they are properly defined and applied throughout the thickness of the beam.

As for implementing the intensity profile of the various beam modes, it may be helpful to consult with other researchers or experts in this field for guidance on the best approach. You could also try reaching out to the COMSOL support team for assistance with troubleshooting the error and implementing the intensity profile.

I wish you the best of luck with your model and I hope you are able to successfully simulate laser forming using COMSOL. Keep us updated on your progress and feel free to reach out with any further questions or updates. Happy modeling!
