meshing stops at 80% and fail

Anonymous — Wed, 04 Aug 2021 22:46:07 GMT

Hi Forum,

I have been having problem with meshing the crane pedestal on a part of the vessel. I have tried changing the geometry and meshing settings and meshing would stop at 80% before the error message pops up. I have another modal that is 90% the same and mesh worked fine on that.

anybody knows what causes this?

Just to update, I have also tried getting rid of all the stuff that is unnecessary, failed again at 80% meshing, see the attached error. any inputs are welcomed!

Hello, sorry you are having these difficulties. I am not sure why your modal study was able to mesh, you should compare mesh settings and note any differences. The defaults for LSS and Modal are the same so I would expect them to mesh the same if you are using the same settings.

The meshing errors you are showing indicate modeling issues. There is a repair tool in the Design environment but you need to ensure that "Capture Design History' is disabled. Right click on the root of the browser to see this option, it may already be disabled if your geometry was imported from another format. You will then see a 'Validate' command under the Inspect menu. The can be used to repair bodes automatically, unstitch bad faces so you can replace them, and remove very small faces/edge which the mesher may not be able to cope with. I highly recommend making a copy of your document and experimenting with this command there, then once you have gotten the hang of using this tool and made some progress with the model, you can make the repairs on your original file.

You can also try using a smaller mesh size since your parts are very thin, but keep in mind this could slow down the analysis if you make the size too small.

I hope this helps, good luck!

Hi Rob,
Thank you so much for your reply!
I have tried the validation and it says no issue detected, re checked interference and it was all fine. Comparing with the old one that worked, i have exactly the same mesh settings, the only difference is that I added a couple of new plates in there, and there were a lot of other similar plates in the old model so i don't think this would be the issue.
Is it possible to send you the file so you can give me some valuable suggestions?
Thanks!
