TransAT Tutorial Manual 10.3. Droplet Impact on a Flat Plate

10.3 Droplet Impact on a Flat Plate

10.3.1 Prerequisites
• TransAT

• TransATUI

• TransAT Python Environment
• Paraview (or Tecplot)

10.3.2 Introduction
In this tutorial, the impact of a droplet on a flat plate is studied. This test case is a demon-
stration of the TransAT Smart Adaptive Run Parametrisation (SarP) module. Solver and control
parameters can be controlled and automatically tuned, as demonstrated by Ghorbel et al. (2019).
In this tutorial the simulation will be run in both normal mode, i.e. without the activation of
the SarP module, and SarP optimisation mode. For this purpose two simulation setups will be
created from a template TransAT project and run.

10.3.3 Launching TransATUI

• Double-click the TransAT icon on the Desktop.

10.3.4 Opening TransAT window
The first step in creating a new TransAT project is naming said project and giving it a location.

• Click to create a new project

• In the next window, navigate to the folder where the project will be saved

• To create a new project folder, click in the top right corner of the window

• Enter a project folder name, say droplet impact, then click to create the folder

• Click to select the folder and close the browser

• Set Project Name to a more explicit name such as droplet impact then click

After clicking , the Mesh & BCs tab will be opened.

The Geo, Mesh & BCs, Input and Execute tabs at the top of the TransATUI window can
now be selected to open the modules to set up a simulation with TransAT.
