Scope of the Theory Manual

This manual covers the theory required to understand finite element based structural simulations in the software. The primary focus is on linear static analysis, mesh generation concepts, material modeling, loads, constraints, solvers, and post-processing.

The scope includes:

• Continuum mechanics foundations.
• Stress, strain, and constitutive relationships.
• Linear elastic material behavior.
• Finite element discretization and stiffness matrix formulation.
• Boundary condition and load treatment.
• Mesh quality, convergence, and element selection.
• Direct and iterative numerical solvers.
• Recovery and visualization of displacement, strain, and stress results.

Topics such as advanced nonlinear mechanics, transient dynamics, coupled multiphysics, and specialized material laws may be documented in separate chapters as the software capabilities expand.
