Macro that can be run by pressing a single button. Routine a number of times using the same model, it is convenient to create a If you need to solve the same system of equations or run an optimization For optimization problems, this means that the solution may be only a local optimum. The solution may depend upon the starting values. This example has demonstrated a very important point having to do with the Excel solver and optimization in general. High accuracy thermodynamic and transport functions for 100's of fluids.Figure 4: Mechanism showing two possible configurations.The 64-bit version increases this limit to 24,000. The 32-bit Professional version can solve 12,000 simultaneous equations. Solves up to 6,000 simultaneous non-linear equations (Commercial version).Operates on all Microsoft Windows operating systems (XP, 7, 8, and 10).A major feature of EES is the high accuracy thermodynamic and transport property database that is provided for hundreds of substances in a manner that allows it to be used with the equation solving capability. The program can also be used to solve differential and integral equations, do optimization, provide uncertainty analyses, perform linear and non-linear regression, convert units, check unit consistency, and generate publication-quality plots. EES (pronounced 'ease') is a general equation-solving program that can numerically solve thousands of coupled non-linear algebraic and differential equations. ![]()
