MSC. EASY5 Strategies for Model Building (or don't do this at home) In a training course we: Cook up problems that are somewhat idealized Build fairly large models all at once Provide detailed instructions, parameter values and I.C.s This optimizes chances for success, efficiently uses class time This may not work for you outside of a classroom setting Start small: 1-4 components). Get that working first Build incrementally: add 1-4 components at a time At each step, carefully consider parameter values and L.C. S, obtain a valid operating point Crawl Walk Run Modeling and Simulation of Gas Systems with MSC EASY5 - Chart 23 MSC XSOFTWARE
