MooseVariableLinearFVReal
Overview
This variable is used for finite volume simulations where a linear system is solved with the following form:
where is the vector containing the degrees of freedom for the declared variable, while and are the corresponding system matrix and right hand side, respectively.
commentnote
This variable can only be used with linear systems and cannot be used for systems which need Jacobian and residual evaluations, such as nonlinear systems being solved by Newton or quasi-Newton methods.
Similarly to MooseVariableFVReal, this variable describes a field which has been discretized using the cell-centered finite volume method and can be evaluated using the functor system in MOOSE.
Example Input File Syntax
To create a MooseLinearVariableFVReal, users can do the following in their input files:
[Variables]
[v]
type = MooseLinearVariableFVReal
[]
[]
Note that unlike the case of finite element variables, the user needs to explicitly define the type of the variable.
