The problem of FEA analysis with P-Adaptive method
The problem of FEA analysis with P-Adaptive method
(OP)
Dear respected Engineer,
I have found something strange about the P-method in cosmoswork professional. ( but may be I have wrong setting)
I found that when I increase the P-Adaptive method,
the polynomial I use 3, then 4, loop 3.
the maximum stress in analysis become higher and higher.
Why this happend?

Is it I need to redesign the corner?

1) if you are confident that the corner is not the point of interest, just ignore it. the stress singularity is just a numerical issue.
2) if the corner is indeed your point of interest. model it with a fillet. Pure sharp corner doesn't exist in the real world.
RE: The problem of FEA analysis with P-Adaptive method
why?
May be I should ommit the point?

I found that I cant doing the fillet corner. The beam I definte in flat corner to represent the weldment, but the critical point concentrate at the flat corner. That is why I say the stress become higher and higher.
