Add GetInternalForce for TetrahedronElement

[epsi1on]

Add GetInternalForce() For TetrahedronElement.
Strain and stress are constant through tetrahedron element, Therefore simple to add this feature...

[epsi1on]

continue from #140,

As you know the strain and stress in constant through a tetrahedron element, But as long as i see, in your output, the stress is not constant through tethrahedrons. Just thinking about the reason... Do you have any idea?

Can we please continue discussion about tetra hedron internal force here: #142 (for future reference) Thanks

Could you send what do you see? Maybe I didnt send the nodes coordinate? And I sent a displacement, I hadnt sent a strain

I think you also sent some stresses. right?
Let me put all files into the repository. then will continue...
Thanks

i did upload files into repository 804e225

here are the files:

@SilberVogel I think we need stress inside each element. Currently stresses are evaluated at each node. and each node is common between several elements, so the internal force of each element is not clear..
Thanks

Cant find correct comand at ANSYS for actual requirements. Will try it more and after send you results.

@epsi1on hope this will helpful
Case 3 element_stress.zip
It contains Principal`s of Stress in [MPa] for each element and they need to be approximated.

Very good, I think this is just right thing...!
let me check. thank you
