mesh convergence for a free mesh (ABAQUS)
mesh convergence for a free mesh (ABAQUS)
(OP)
hello guys,
How do you go about doing a mesh convergence test for a mesh created through free meshing?
I picked a specific point in the model and tried to do a von mises stress convergence at that point. But the problem with this is that I have only approximate global mesh size on the x axis (free mesh). Also, I don't think this is reliable.
Has anybody got some ideas?
also here are my values from a dodgy convergence test I just carried out:
Global Size(Von mises)
100 (66.98)
80 (81.21)
50 (61.74)
25 (103.05)
20 (106.53)
15 (103.12)
10 (118.57)
5 (133.88)
2.5 (135.12)

I guess, I am looking unnecessarily for a nice smooth curve like the one below (but with stress):

so I should work with percentages ? rather than trying to get a smooth graph.
because the stress went up and down on these global sizes :
100 (66.98)
80 (81.21)
50 (61.74)
25 (103.05)
20 (106.53)
15 (103.12)
