Hello Khalid, In version 5.2a, there is a ready-made interface for magnetostriction in the Structural Mechanics Module: https://www.comsol.com/release/5.2a/structural-mechanics-module Best regards, Jeff

Hello Jeff, Thank you very much for your reply. Right now I have only access to comsol 5.1, and I want to couple those two physics (solid mechanics and magnetic field). Both depends on the other. Would you please tell me how can I do that?

Frankly, my suggestion would be for you to first investigate whether 5.2a does what you want or not. If it does, I would say it is rarely worth it to reinvent the wheel, but if you do choose to (or have to) go that route there are plenty of examples in the documentation and application libraries showing how to couple physics, including two-way couplings. Best, Jeff

[QUOTE] Dear Researchers, I am trying to implement linear magnetostriction in comsol as suggested in this link: https://www.comsol.com/paper/coupled-structural-and-magnetic-models-linear-magnetostriction-in-comsol-6357. I am trying to couple both magnetic field (mf) module and solid mechanics (solid) module in comsol 5.1. Now my problems are: (1) I want to include the strain dependent magnetic field term in the AC/DC module. I was trying to include that strain dependent term in the initial field description as: A = (-lambda_s*solid.eXX*x + lambda_s*solid.eYY*y)*z_hat so that I would have a strain dependent magnetic field. Is there any better way to include that strain dependent magnetic field term? (2) Secondly, I have a magnetic field dependent initial strain term in the solid mechanics physics module. But the problem is, I want to couple this physics together, how can I do that? It seems that comsol is always solving the magnetic filed calculation first and then solving the solid mechanics physics. I am eagerly waiting for your response. Thank you. Khalid [/QUOTE]
