Fluid Class
This class defines a fluid object with properties such as density, viscosity, and compressibility. It provides methods to access these properties and allows initialization with specific values.
Contents
Methods
- Fluid: Constructor to initialize the fluid object. If only the id is provided, other properties are set to their default values.
- getDensity: Returns the density of the fluid.
