4.2 Guiding Principles

1. Units First: Define consistent unit system before any modeling
2. Mesh Quality Determines Accuracy: Perform mesh convergence study for critical results
3. Nonlinearity Increment Control: Use automatic time stepping for nonlinear problems
4. Validate Before Trust: Compare with analytical solutions or experiments
5. Parameterize Everything: Use parameters for design exploration and optimization
