Module fem_api 

Finite Element Method (FEM) simulation API for Python interop.

Provides a standalone structural mechanics FEM solver supporting:

• Linear elastic 2-D triangular elements (CST - Constant Strain Triangle)
• Assembly of global stiffness matrix
• Dirichlet boundary conditions (fixed DOFs)
• Nodal load vectors
• Conjugate Gradient iterative solver
• Displacement, stress, and strain output
