COMSOL bug ! due to the prescribed velocity in Solid mechanics

Please login with a confirmed email address before reporting spam

Dear all

I apply a precribed velocity at one boundary with a very small value, 1e-20m. However, at the initial time step, the geometry distorted extremely, which did not make any sense. I am wondering whether others have encountered such issues? and how did you solve it? Is it a bug of COMSOL? It is so weird.

hhh

Thank you for your help.

Yu
