Tetra and tria element
Tetra and tria element
(OP)
After using FE methods for 15 years, I have been inactive from FE-analysis for some years, but are now again invovled in a composite material analysis project of a marine structure. I remember when using MSC/NASTRAN some years ago, a lot of scepticism arose from using tet4 and even tet10 elements. (Today I am using NX/NASTRAN) I have recieved a FE model from a customer, with almost only Tet10 and tria6 elements, and I have noticed that this is not unusual today to use these elements. My question is: Are tet and tria now accepted because of convenience or is the quality of the elements so much improved the last 10 years that stress results are acceptable? Or are the same elements used with just denser meshes?
Thanks for any input. Especially from long time FE specialists.

tet10s (and tri6) good

It takes a bit of time to prepare geometry but it's worth doing in order to generate a brick rather than tet10 mesh.
