This is the last post of series simulating dynamic tanks using EMSO simulator. The first one shows the direct implementation of the dynamic tanks case using the modeling language of EMSO that applies concepts of object-oriented languages (part 1). The second one used (part 2) resources of EMSO GUI to link models to figures and create a block diagram of the process from the connection among them.

This is the second part of our text “Simulating a dynamic tank in EMSO”. The first part shows the basic theory about EMSO modeling language applied to model a dynamic tank. The code to a single tank was implemented and expanded to a set of tanks in series.

This post starts to our section of HOW-TO texts. My objetive with this specific post is to introduce using some free tools to different applications.

A classic problem in process engineering is the case of a dynamic tank where the output flow is proportional to its level (Fig. 1). This example is part of EMSO tutorial so that more details would be to consult in the EMSO manual.

In this approaching, the problem of dynamic tank involves 3 variables and 2 parameters such below:

ASCEND is an **open source** modelling environment and solver for large or small systems of non-linear equations, for use in engineering, thermodynamics, chemistry, physics, mathematics and biology. Solvers for both steady and dynamic (NLA & DAE) problems, are provided. It offers:

– An object-oriented **model description language** for describing your system,

– An interactive **user interface** that allows you to solve your model and explore the effect of changing the model parameters, and
