Yes, you can add an eigenfrequency study to the FSI in COMSOL model. Here's how you can integrate it: Add an Eigenfrequency Study: In the Model Builder, right-click the Study node and select Add Study > Eigenfrequency. This will allow you to calculate the natural frequencies and mode shapes of the structure, like the oscillating beam in this case. Multiphysics Coupling: Make sure the FSI is properly coupled with the Structural Mechanics and Fluid Flow modules. The eigenfrequency study will focus on the structure's response (oscillating beam) without fluid flow, or it can include fluid effects if needed. Boundary Conditions: Define the appropriate boundary conditions, such as fixing certain parts of the beam or specifying interaction forces between the beam and the fluid. Run the Eigenfrequency Study: After adding the study, run it to analyze the natural frequencies of the beam while interacting with the fluid.
Thank you for your interest! Unfortunately, I’m not able to share the file directly here, but I can guide you through the steps to create a similar model in COMSOL. If you have specific questions or need help with any part of the simulation, feel free to ask!
The Computation time depends on your computing power i.e. RAM, Processor and GPU as well. If your solution is not converging please check your boundary conditions and mesh refinement.
When I do thenfirst difference and select the ellipse to subtract it dissapears and I can't complete the second difference.
hello, what is the moving mesh domain selected? the one in definitions in deforming domain. thanks
The moving mesh, or deforming domain, is the main region where the beam oscillates.
can i add eigenfrequency study to this interaction?

What is selected in deforming domain
The selected deforming domain under moving mesh is the main region where the beam oscillates.
Did anyone do this for 3D?
Haven’t seen so far.
Can i get file?

SAI come back, do you have comsol license?
I am back 😃
Its taking a lot of time and the solution has not converged .Why?
