Detailed Description

Material holding equation of state.

Pressure and sound speed are computed in initialize function, so the EoS does not have to be evaluated manually. If this is necessary for some reason (when setting pressure-dependent initial conditions or checking if we selected correct EoS, for example), functions evaluate and getEos can be used. This is not part of the IMaterial interface, so dynamic_cast have to be used to access it.

Constructor & Destructor Documentation

◆ EosMaterial() [1/2]

NAMESPACE_SPH_BEGIN EosMaterial::EosMaterial	(	const BodySettings &	body,
		AutoPtr< IEos > &&	eos
	)

Creates the material by specifying an equation of state.

Equation of state must not be nullptr.

Definition at line 13 of file Materials.cpp.

◆ EosMaterial() [2/2]

EosMaterial::EosMaterial ( const BodySettings & body )

explicit

Creates the material.

Equation of state is constructed from parameters in settings.

Definition at line 19 of file Materials.cpp.
