I've been trying to deal with a 20 pc. assy., but currently crashing. I cannot post pics nor assy/prt files. This is essentially a flat plate w/both simulated fasteners and solid screws into a fixed mounting structure. Plate has a pressure load applied. The fastener preload iteration took 8 hrs to run on 'quick check'...
I need this to RUN!!!!!!!!!!!!!!!!!!!!!!
At this point, no preload on the solid screws is necessary
I feel this has taken far too much time....approx. ~100k elements, (if I can even get it to complete the mesh).
To prevent chattering, I've tried to match tols by switching all part accuracies from 'relative' to 'absolute'. Using def. tol of 1e-4,
refined meshing on rounds, cbores, thru holes of interest...thru Autogem....used a lot of 'Max. Elem Size' and 'Exclude Singularties' @ re-entrant<150 deg.....
Nodes? I have laid down some of these - There seem to be directional arrows....right click in collection box and "fix"...did this....
Autogem Settings - "detailed fillet modeling" is checked...
There is a skeleton with curves I used to trace the sim region...this seem ok....
I've gone down to the part level and refined meshes there, am intending on using these piece part meshes at the top level...am I wrong to assume this?
How is it that I can't get this to kick, but every little demo and presentation is always just sunshine & smooth sailing....
Now - the ANSYS group is chomping at the bit to get their hands on this and I have no grounds to hold them at bay..I have until Fri. to get this assy. running...
btw- brand new M6800 w/32Gb...so it's not the hardware...
cpu 'use all'
Q: Comments? methods?
Thanks for your attention and review..
