Description

Do you want to know how to automate the launch of a CFD simulation? Do you want to quickly and easily evaluate hundreds of configurations of your product? By coupling Particleworks and Python all of this becomes possible.

This course deals with automation techniques (using Python) and optimization of a fluid dynamics simulation based on the Moving Particle Simulation (MPS) approach.

After an introduction to Python and the Particleworks API (Application Programming Interface), pwpy; the classes, functions and objects of the API will be presented. In this way, it will be explained how to interact with the simulation using the script.

Having become familiar with pwpy, we will discuss examples implementing the simulation steps (preparation of the simulation, numerical settings, definition of kinematic laws, preprocessing, launch and postprocessing).

Then, we will discuss the automation of the screening of various operating speeds of an input shaft inside a gearbox.

In the last part of the course, the integration of the Python/Particlworks script with an optimizer will be presented.

Target Audience

The training is designed for engineers and designers that would like to automate the Particleworks simulation process and post-processing workflow. Additionally, the training provides an introduction on how to couple Particlworks with an optimizer.

Pre-requisites

Basic knowledge of fluid dynamics and Particleworks are required. Moreover, familiarity with Python and object-oriented programming is suggested.
