Re: Number of nodes for high order tetrahedral element is larger than 10
likely usinghte standard mesher - drop the mesh tolerance to say 5% of say the smallest element - it is by default set at 5% of whatever the global element size is. the merged node radius is capturing more than one node.

Re: Number of nodes for high order tetrahedral element is larger than 10
It was with curvature based mesher. This error has seemed to sort itself out, possibly by just making the mesh finer.
I now have this error which really baffles me.

I would use the standard mesher.

Re: Number of nodes for high order tetrahedral element is larger than 10
Please see pictures. When I use the standard mesher (shown first) certain faces disappear, but when I use the curvature based mesher they show up when I show the mesh. Does this mean they failed to mesh, even though I did not receive any error message?
I am confused because all of this faces are part of a single knitted surface.
Is this indicative of a larger problem with this surface geometry?

Those are shell elements. It take it, it is a mixed mesh study. The updates on shells is a bit problematic. You can try "update all components" not likely to work but it might. If that fails make a new study and drag all the items to the new study and the surfaces that are missing will likely mesh.

Yes, they are shell elements and it is a mixed mesh study. Shell elements have been giving me many headaches.
I will try the new study and see if that helps.

Bill's recommendation worked for me. Unfortunately, the software seems unstable such that the problem comes back. I have put in an enhancement request to fix this. If enough people request this perhaps it will get fixed soon. Good luck.

Hello Ian,
This looks like a problem (Element group label is assigned 0) which already reported in our database under SPR 606276.
Tech support has given me the following workaround which worked for other people
"However accepting the message, closing the dialogue box and selecting Run for a second time seems to work OK."
For another customer with a similar message the following solution worked: Using standard mesher works. Again to fix the disappaearing faces during meshing process follow Bill's solution of using a smaller mesh tolerance and/or size.
If you still have problem, please go through your reseller or technical support resource to file this problem with the model against the aformentioned SPR so development can take a look at your model to suggest workarounds or fixes.
Thanks.

Hello Ian,
Your original error regarding number of nodes for high order tetrahedral element is larger than 10 was fixed in SolidWorks Simulation 2012 as part of fixing SPR 597011.
Thanks.
Hari
