In.the.early.stages.of.system.design,.termed.the.conceptual.design.phase,.there.are. typically.multiple.competing.alternative.designs.to.be.evaluated,.selected.among,. and.merged.or.decided.against..In.this.process,.simulations.of.these.alternatives. are. often. used. to. embed. the. conceptual. designs. under. consideration. into. their. intended.future.operating.environment..Computational.representations.and.models.of.structures,.of.propulsion,.of.process.control,.and.of.aerodynamic.systems. are.commonly.used.to.explore.variations.in.new.conceptual.designs.for.product.or. process.enhancement..Modeling.is.a.strategy.for.relatively.quickly.understanding. the.behavior.of.a.system.in.cases.where.the.complexity.in.its.operational.context. makes.analysis.difficult.or.impossible..The.usefulness.of.a.model.is.determined.by. its.ability.to.explain.and.bring.a.focus.to.observations,.to.simplify.explanations,.to. predict,.and.to.inspire.discovery.
