ChassisSim – what you need to do to get going

April 4, 2013

ChassisSim is a highly advanced piece of vehicle dynamics software. Consequently when you start using it for the first time it can be a little daunting about where to start. Believe it or not it’s not as hard as you think.
Getting started with ChassisSim is actually a very simple straight forward affair
Step-1 – Create a Directory structure.
If you don’t know where to store things and account for things you’ll get confused very quickly. Consequently when you saving car files, creating monster files and circuits the following directory structure is recommended,
C:\ChassisSim Technologies\Models\Car Name\Circuit\Event.
So for example if you have an F3 car for instance and you ran it at the April 2012 Test at Sebring, the directory structure I would suggest is,
C:\ChassisSim Technologies\Models\F3\Sebring\April_Test_2012
This structure is bullet proof in terms of the running of ChassisSim.
Step – 2 – Start from a template.
Starting from a well known template ensures you are starting from a well sorted model. Consequently if anything goes wrong it can be quickly rectified. To achieve this all you need to do is click on the Car drop down box and select from the available templates. Then all you do is one by one morph your car’s setup and parameters into this car file and save it in the directory we established in Step 1.
Step – 3 – Create a monster file
The monster file is your link between actual data and the modelling features of ChassisSim. A senior member of the ChassisSim community described a good monster file as the foundation stone of everything you do with ChassisSim. The following video shows you how,

Place this monster file in the folder we created in step 1.
Step – 4 – Run the Auto Modelling features.
The one touch modelling feature will provide a first pass of the aeromap and the tyre parameters. If the template is very well sorted then this step can be omitted. However do it as a double check anyway. The following tutorials shows you how to get the most out of these features,

and this shows how to refine the results,

Step – 5 – Create the circuits
Once you have a ball park model you can create a circuit model. When creating your initial circuit model put all your circuit files in the directory you created in Step – 1. The following video shows you what to do,

Summing Up
If you follow Steps 1 – 5 you’ll have a baseline model you can use to get going. Obviously there’s more refinement you need to do, but this will get you going with a model that will achieve good correlation and give you a representative environment to get going with. Remember the key to simulation is to get started and these steps will set you well on your way.
