Hi
Try two remote displacements, so one for each lug (scoped to the inside lug face) - for both, restrain all translations (X,Y,Z =0) and rotations about X (=0).
The try to solve with a smaller mass - say 1 kg to see that the system is balanced and can solve.
When it does, include large deflections (ON), and run with the full weight - set substeps :

Also include an image in the next post so we can see how the structure is supported.
Thank you
Erik
