deer all:
I have built a same cantibeam model in OS ,abaqus and ansys to validate the precision of brick element in OS.
it is acceptable of the 20 node brick elements (both TLFDD20nBrickElement and brcik20N),
while it is not perfect in 8 nodes bcrik elements model.the displacements of the 4 free nodes are all negative ( the concentrated force is -Y axial)in abaqus and ansys,
while there is a positive displacement in OS model!
I don'nt know why .actually,
the stiffness matrix of OS is better than abaqus (I get the sttiffness matrix by hand-calculation because the model is so
simple, it is a cube and only has 1 element),
which one is wrong?
can you give me some suggestions.thank you !

compare the os with abaqus (brick elements)
