Code_Aster fails on blended corner

Hello,

I'm brand new in Salome. I'm fiddling with different test cases and I found one "no-go" example. I try to run simple static analysis (generated via Linear Elasticity Wizard) and it seems the topology of the mesh on blended corner (regardless of the used algorithm / discretisation density) can't be interpreted by Code_Aster solver. Here goes the actual error message from .mess file:

Problematic node#75 is the yellow one on the corner in the picture

I can't exactly understand the error message (I don't speak French). Did anyone have similar problem? Do you know how to resolve this issue (other than simplifying the model by suppressing all fillets )

Hi,

attached are the files.

I tested several different models and was able to recreate the problem every time on blended corner regardless of constraints applied or other part topology. I've used wizard to create the .comm file.

Happy Easter!!
