It seems like you are encountering a specific problem with a COMSOL Multiphysics simulation related to a feature called "Stationary Solv." To help you troubleshoot and solve this issue, you can follow these general steps:

ü Ensure that your model geometry is correctly defined, and all boundaries and domains are properly assigned.

ü Double-check the material properties you have assigned to your domains and boundaries to make sure they are accurate.

ü Verify that the boundary conditions are correctly specified. Ensure that you have set up the appropriate physics boundary conditions for your simulation.

ü Pay attention to the mesh quality. Make sure the mesh is fine enough in areas where you expect significant variations in the solution.

ü Review your study settings, making sure that the "Stationary" solver is the correct choice for your simulation.

ü Check the solver settings, such as the solver type, tolerances, and convergence criteria. Adjust these settings as needed.

ü Ensure that you have provided reasonable initial values for your variables if required.

ü Make sure that you have imported or defined accurate material data for the components involved.

ü Examine any source terms or boundary conditions you have specified. They should reflect the physical behavior of your problem accurately.

ü Ensure that you have set the correct units and scaling for your simulation. Inconsistent units can lead to convergence issues.

ü Check the logs and error messages provided by COMSOL. They can often point you towards the source of the problem.

ü If the problem is particularly complex, consider simplifying your model to isolate the issue. Remove or disable parts of the model to see if that helps identify the problem.

ü COMSOL has an extensive knowledge base and user forums where you can search for solutions to common issues and ask for help from the community.

If you can't resolve the issue on your own, consider reaching out to COMSOL support for assistance. They can provide guidance on troubleshooting and resolving specific simulation problems.
