Nonlinear Supports #7

Open denisgomes opened 4 years ago

Implement one directional supports. Supports with gaps and friction.

For each non-linear support and each loadcase (each iteration consists for going through all the non linear supports and doing the steps below, each item below is one iteration):

  1. Initially a non-linear (+Y) support is converted to a linear full Y support.

  2. If the solution shows a (-Y) load on the support, the support is modeled correctly. If not, the program gets rid of the support altogether and tracks the displacement at that point.

  3. If the point shows a (+Y) deflection, this support is modeled correctly for this loadcase. Else, the stiffness matrix is reset to a full Y.
