CFD Apps - https://cfdapps.appspot.com - is an online portal to enable advanced CFD modelling using simple application specific submission process.
This presentation provides a getting started user guide for the use of the Vehicle Aerodynamic Study portal. This portal is dedicated to the simulation of the vehicle aerodynamic, in particular airflow path and extraction of drag and downforce parameters.

Presentation Objective(s)
• Ensure that customers are confident in
how to prepare their geometry and use the
portal;
• Reduce the number of "false" or
"erroneous" submissions.

Geometry Preparation
• If submitting geometry using STL file
format:
• Use meter units;
• Ensure that parts are correctly splitted and that the
solid are named correctly (ie as per the previous
slide);
• If submitting geometry using the SketchUp
file format:
• Ensure that group and components are named
correctly.
