- variableVariable labelling the weak form this kernel is added to
C++ Type:VariableName
Unit:(no unit assumed)
Controllable:No
Description:Variable labelling the weak form this kernel is added to
MFEMDomainLFKernel
Overview
Adds the domain integrator for integrating the linear form
where is the test variable and is a scalar forcing coefficient.
This term arises from the weak form of the forcing term
