Hello everyone. Is there a way to share the displacements and rotations among two physics, in two point non coincident ?

Best regards.

Hi Enrico,

Yes, you can use a nonlocal coupling. See COMSOL Multiphysics 6.1, Reference Manual, page 375 and following.

Best,

Jeff

Hi Jeff. Thank you for your answer, is it possible using the tool "probe point" where I could transfer the displacement from a physics to other physics ? Will I get the same result with nonlocal coupling ?

Thanks !

Hello Enrico,

Probes are not a feature of the software I have used much, so take this with a grain of salt. But I was able to use a point probe in the attached toy model to cause a volumetric heat source to be related to the electric potential at one point. So it does look like it should work for you. Try it out, and if it does not work for your purposes, for a more definitive answer please contact our support team.

Best,

Jeff
