Hi,

I encountered a problem about "Automatic remeshing" with "deformed geomerty" and Time-Dependent Solver

When I ran the program, Comsol always displayed a Error:
Unsupported operation on this type of object.
-Feature: Time-Dependent Solver 1 (sol1/t1);
-Error: Unsupported operation on this type of object.

i try all possible mesh quality expressions and resonable threshold vaules, it seems when the program reaches this value,

the above error happens immediately.

Who can tell me what's wrong?

Your information and help is deeply appreciated!

Luyao

I'm having exactly the same issue. This must be a bug as I encounter this by simply enabling the "Automatic remeshing" checkbox in the Time Dependent step for the Laminar 2-phase flow with moving mesh. What's the best course of action?

Hi Luyao,

maybe you've solved the problem already. Just want to share my limited experience with this type of error message. It might be the problem with geometry.

for some reason, once i tried to use "right click "Geometry>>Virtual Operations" to compose 2 objects into one. Then I got the same error message. So "Automatic remeshing" doesn't support geometry with "Virtual operations".

That's my experience with this type of error. Hope it could help!

Thank you very much! Chunyan.

I also noticed this issue, like you said, "Automatic remeshing" doesn't support "virtual operations".

Unfortunately, I haven't found a way to solve this problem, just avoid the "virtual....".

Hope COMSOL developer can pay attention to this "bug".

I do not think this has much to do with automatic meshing. I get similar error with both Physics-Controlled mesh and user-controlled mesh.
