class m_boundary_conditions.Point_Fixed_Pressure

Bases: SubDomain

inside(x, on_boundary)

Returns:

Identifies the node that is located at the top left corner of the domain, where the pressure will be anchored in case of no free surface boundary condition.

m_boundary_conditions.apply_temperature_BC(sCG2, boundary_parts)

Applies the Dirichlet boundary conditions for the heat equation.

Parameters:

• sCG2 – function space for the temperature

• boundary_parts – how to describe that….

Returns:

A list of the Dirichlet BCs (temperature) that will be given to the

• the stationary heat equation, see m_equations.Equations.equation_heat_ini()

• the time-dependent heat equation, see m_equations.Equations.equation_heat()

m_boundary_conditions.apply_velocity_BC(V, boundary_parts, top_left, t)

Applies the Dirichlet boundary conditions for the Stokes problem.

Parameters:

• V – function space for the Stokes problem

• boundary_parts – how to describe that….

• top_left – coordinates of the point where to fix pressure if no boundary is free surface

Returns:

A list of the Dirichlet BCs ( velocity) that will be given to the Stokes problem, see m_equations.Equations.equation_stokes().
