Convergence results analysis
I have the simple model with weld seam. So, my goal is to know the max stress in the place of concentration.
I use convergence to figure out how small mesh should be to get accurate result of the stress in that place.
I have set 5 % allowable change and 10 refinement loops. After 10 loops i got the following results.
The maximum stres incrised significantly from 557 MPa to 9800 MPa and allowable change of 5% hasn't reached yet.
How can this results might be assesed?
Is it possible that the Ansys can't calculate the mesh properly to get 5% change?
