Reason
As the development and implementation of the electromagnetic module increases, there is a need to include the option to defined the curl and coupled curl operators as AD functions. This helps to avoid errors involving more complex formulations that include the curl of variables in lieu of using hand-coded Jacobians.
This closes Issue #29868
Design
A function named
adCurlSln()
that calculates the curl of a variable as an AD variable was included in the MooseVariableData file. This enables the used of the curl operator on AD variables and coupled AD variables. To ensure that the AD curl operators are working as as intended, tests usingtype = 'PetscJacobianTester'
were added.Impact
The inclusion of a AD versions of the curl and coupled curl operator will allow for faster development of additional physics into the MOOSE framework that utilizes the curl of variables.
