This is an old revision of the document!
POL(I)FLOWS is an object-oriented numerical simulation software developed by Marco Lucio Cerquaglia at the Department of Aerospace and Mechanical Engineering of the University of Liège during his PhD, conducted in the MN2L research group.
The code is for the moment limited to the simulation of 2D incompressible flows based on a Lagrangian approach in the spirit of the so-called PFEM (Particle-FEM) method (see e.g. http://www.cimne.com/pfem/).
The core of the code is developped in C++, while the user interface is written in Python. The C++/Python interface is managed by SWIG.
This small wiki mainly illustrates how to write the input Python (.py) file in order to run a simulation properly. No details about the implementation are given herein.
NB: This document does not represent a manual and it is intended for “aware” users!
NB2: please note that the code is developped in a Windows environment, so all the “operational” commands described hereafter (not the input file structure) are intended for Windows users. Nevertheless the code should be 100% portable so, in the very next future, it should work fine on Unix/Linux systems without major changes, even if never tested so far!
If you want to have an idea on how the code works, the first thing you should do is take a look at the Flowchart…
