• I recall importing it in and leaving it with linear elements while I mirrored and stitched the sections together. Then, I would use custom refinement to bump up the refinement in areas of concern. Also, since I'm using composite properties I had t…

• It the nature of the beast (FEA using laminates with shells). I doubt any product out there has a better solution. It would go a long way to help if the tree view didn't re-initialize when changes were made and there was some way of ordering the c…

• I can confirm that... Back during the Lisa version, I had a utility program that would read the output file and change the input file and do a real basic version of a compression only support. It would only work on a plane. I never added the requi…

• The frustration isn't too bad. :-) I'm getting spoiled with Mecway. I would not have even attempted a model of this size to run at all on either the IBM-3090 or Cyber super computers I had access to back in the 80's and 90's.

• I would like to suggest that there be some way to pause and evaluate an on-going analysis that uses compression-only-support. That after I look at the intermediate results, I could choose to stop the analysis (keeping the current step’s results) or…

• Welcome Ormond, As a temporary work-around... I don't know your specific tools or situation; however, I know this works for the stl format and I'm thinking it would work for dxf. 1) Export from your CAD program individual layers into separate dxf…

• Hi Victor, Just for grins and see if it starts converging, I ran a series of tests just changing the Convergence tolerance. As you mention, it did finally and suddenly drop. Here are some stats... Tolerance Iterations Time Converge 0.1 …

• Is there a way to pause an ongoing analysis during a convergence step, save off the results and then continue on?

• Hi Victor, Thank you for your quick reply. In the old days, we never went non-linear.  So, your explanation is definitely helping me get there. Am I correct in assuming that this summation of “all”… is all the nodes that make up the contact co…

• By far and away the most highly stressed components on the Z40 are the Swing Keels. For those not familiar with sail boat jargon, this is a wing that runs vertically in the water so that the lateral loads on the sails are resisted. Instead of crab…
