Finite-element and topology-optimization method, independent of any program: formulating a study, meshing and convergence, boundary conditions, structural response, reading stress and strain, and stating and interpreting an optimization problem.
Treat every boundary condition and load as a modeling assumption that must match the real support and loading it stands in for, not a default the software supplies.
Trace one continuous argument from the physical question through idealization, discretization, and solution to what the outputs can actually support.
Match element type and density to what the study needs to resolve, and prove convergence rather than assuming a fine mesh is adequate.
Report a stress or strain result with the invariant, location, and material-model context that make it meaningful, rather than a single unqualified number.
Connect a loading scenario to the structural response mode it actually produces — stiffness, stability, or strength-limited — before selecting an analysis type.
State the optimization problem precisely (objective, constraints, design and frozen regions, manufacturing restrictions), check the analysis model before blaming the optimizer, and treat the converged result as a design proposal that still needs re-verification. Program-independent; the program plugin supplies the syntax.
