tetra10 to hexa20 connection
tetra10 to hexa20 connection
(OP)
Hi all,
I'd like to find a way to couple tetra10 and hexa20 elements in a region.
1- Is there a pre-processor where I can do this coupling, selecting e.g. the surfaces?
2- Is there a algorithm to write an equation between the middle uncoupled nodes of tetra10 and let's say corner nodes of hexa20?
3- Or anything.
Thank you all in advance.

In joining incompatible elements like tet10's and hex4's you will only get continuity of displacement. The rate of change of displacement with position (i.e. the first differential of the displacement function) = strain and hence stress will not be continuous. Thus you cannot expect to get any valid results for stress on and near the join.

My area of interface is far away from this region. You won't get a correct stress distribution at the interface as you pointed. What if my point of interest is far away and I have at least 5 mesh layers between this joint region and my point of interest.?
Thanks for your help.
