Detailed Description

struct MeltPoolDG::CompressibleFlow::ExternalFlowForce< dim, number, n_species >

An abstract interface for defining external forces acting on the fluid that must be evaluated and incorporated during the cell loop of an explicit time integration scheme.

This struct serves as a base for user-defined external fluid force models. Any derived class must implement the core functions: value(): Invoked at each quadrature point to compute the contribution of the external force.

pure virtual

This function computes the value of the external force contribution for the balance of mass, momentum, and energy equations at the given set of points. The returned value then contains the body force as given in the respective governing equations and can directly be added to the right-hand side.

Parameters

time_step_size	Size of the current time step.
cell_batch_id	The ID of the cell batch for which to compute the external force.
points	Coordinates of the points at which the external force is evaluated.
w	Conserved variables at the corresponding points.

Returns

The computed contribution of the external force to be added to the conservation equations.
