Does anyone have an idea why I might be getting this error message in COMSOL?

Does anyone have an idea why I might be getting this error message in COMSOL?

Does anyone have an idea why I might be getting this error message in COMSOL?

(OP)
I have been given a model that is used to model a unit cell representing a large repetitive structure by using "Cell periodicity function" - which calculates the effective material properties of said structure.

Error message I get if "parametric sweep" function is turned off.



Boundary similarity: src2dst_bp3_cp1_sim5 mentioned in the error message



When parametric sweep is enabled, it runs, but abnormally slow, which leads me to believe there is something wrong with the model


RE: Does anyone have an idea why I might be getting this error message in COMSOL?

According to the error message, source and destination (Comsol’s equivalent to master/slave or primary/secondary terms known in FEM) are not compatible. Check their definitions carefully.

(OP)
Is there anywhere I can check what the source and destination are defined as?

And is it in any way similar to slave/master surface in abaqus?

RE: Does anyone have an idea why I might be getting this error message in COMSOL?

Check the definition of periodic BCs, that’s probably where the error lies. General concept is equivalent to that used in Abaqus.
