oscillation in triangle-6 node mesh #6

Closed yangbai90 closed 4 years ago

yangbai90 commented 4 years ago

The oscillation is observed in the triangle-6 node mesh, where the second order shape function and related gauss point integration rule are involved, the result looks like below:

tri6

The possible reason could be the generation of the guass point. Thereby for this case, it should be improved definitely!

This bug is fixed in 512b2ef1211dc22b33239883e9b9c3b0fccc02ff, now the result looks much better:

test

Now the tri6 mesh is ready for the simulation.
