Hi eps1on, In a real structure the different elements, beams, columns and plates or shells are integrated, in few occasions an isolated plate is found. I make this initial comment...

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

Continue from #140 add to this file: https://github.com/BriefFiniteElementNet/BriefFiniteElement.Net/blob/master/Sources/BriefFiniteElementNet/Utils/MeshImport.cs just need an example .msh file.

enhancement

add support for PartialNonuniformLoad into TriangleElement. Add example to the documentation: https://github.com/BriefFiniteElementNet/BFE.Net.devdocs/blob/master/docs/loads/elementLoads/partialnonuniformload.rst#id1

add some validation for ``QuadrilaturalElement`` https://github.com/BriefFiniteElementNet/BriefFiniteElement.Net/blob/master/BriefFiniteElementNet.CustomElements/Elements/QuadrilaturalElement.cs and https://github.com/BriefFiniteElementNet/BriefFiniteElement.Net/blob/master/BriefFiniteElementNet.CustomElements.Test/QuadrilaturalElementTests.cs

Newmark-beta method is used for finding the response of a structure with known stiffness, mass and damp matrix to external excitation like dynamic force and dynamic settlements (earthquake which vibrates...

enhancement

Add an example for mesh with TriangleElement. A polygon surface with holes and constraints that uses Deluanay Triangulation for mesh.

enhancement

remove `Model.Solve()` (move it into Legacy project) and only use `Model.Solve_MPC()` as Model.Solve is old and cannot solve models with MPC elements

As discussed in #124 dynamic analysis have no complete implementation yet, but it would be good for finding stiffness, mass and damp matrices of a model and manually so some...

EDIT: ### Milestone 1 * `BriefFiniteElementNet` / `BriefFiniteElementNet.Common` - [ ] Remove obsolete code. - [ ] Fix not fully implemented classes that use `Obsolete` attribute. - [ ] Inspect...
