I am simulating a RC beam, which I want to load a displacement of 4mm/s, I do not know how to implement this in Comsol. Should I use "prescribed displacement"? In addtion, I have met the error ' Iteration of finding elasto-plastic strain variables did not converge" when I used the "prescribed displacement". Thank you.

Hello,

Indeed the "Prescribed displacement" condition is the boundary condition to impose a displacement.

Please find more information about the error "Failed to compute elastoplastic strain variables" in the following knowledgebase: https://www.comsol.fr/support/knowledgebase/1150/

For more help, don't hesitate to contact the COMSOL technical support.

Regards,

Mickaël
