Modeling and computer simulation are important interdisciplinary tools. Recall that modeling means to find relations between systems and models.
Computer simulation is the process of implementing models on computers.
To do this, you must have an appropriate simulation tool. Go back Modeling and simulation tools Forty or fifty years ago, a simulationist had to be a mathematician and a programmer. Now, a good simulation software should do the task as simple as possible. What the simulationist must understand is the structure and the dynamics of the modeled system, and the aim of all the simulation task. It is not an easy task to select a good software tool.
