FVMatAdvection

Computes the residual of advective term using finite volume method.

The FVMatAdvection kernel is similar to the FVAdvection kernel except that:

  • the velocity is a material property instead of a constant vector, so it may vary throughout the domain

  • an advected quantity

In order to solve for the velocity, one needs to add a VariableMaterial, such as the INSFVMaterial to store a copy of the velocity variable as a material property.

As we are expanding the functor material & variable capability, having the velocity as a material property will no longer be required.

Example input syntax

In this example, the kernels are set up for a steady state advection problem of both momentum and mass. For the former the advected_quantity is set to the momentum. This case uses a constant unit density. Please refer to the Navier Stokes module for more advanced fluid flow capabilities.
