A model must have a number of key components to successfully run a simulation.
Some simple rules for constructing a model are:
- All pipes in a model must be connected at both ends to another pipe, unless connected to the surface or to a tank or a to spray or ‘blanked’ off as a closed end.
- Any fixed flow must not restrict another fixed flow elsewhere in a model, or be overly restricted by an impassible high resistance.
Errors contributing to the above conditions account for around 90% of simulation errors and problems noted in Pumpsim™ (from Chasm Consulting observations)
Overview
There are many different ways to build a computer model. Pumpsim™ utilises a visual approach to creating models, and the fundamental structure (shape) of models can be built either by hand with the mouse or imported from a CAD program.
While a model can be built schematically in Pumpsim™, it is highly recommended building a true-to-scale 3D model if possible to allow Pumpsim™ to automatically use parameters such as size, length and depth for simulation.
The information in this chapter explains only the basic techniques to establishing working models. To create a truly representative model, pipe sizes and resistance must be accurately established and many other important factors such as junctions considered.
