Introduction

This chapter contains an overview of the resolution setup for various types of vehicles in ultraFluidX.

The best practices presented in this chapter are vehicle-type-dependent. In the first sections, we will focus first on passenger cars, and then motorcycles and commercial trucks in separate sections.

For commercial trucks, we will make a note of different tractor design types (cab-over, long-nose) and how to handle them.
