Moving or travelling boundary condition in MOOSE framework

[Anil Kunwar]

Hi All,
Is the parsed function of MOOSE  capable of moving a heat source (e.g. laser scanning) ?
As function = f(x,t), the requirement in the moving heat source is that the previous point should be forgotten with newer timestep.
 Is there any related piece of C++ class related to these moving boundary conditions in MOOSE?
What things must be considered here?


Yours Sincerely,
Anil Kunwar

Sure - if it's an actual boundary condition (like, it's applied on the boundary) then it's pretty straightforward to do with a parsed function and FunctionBC.

If it's a source in the interior of the domain then you have two options depending on what the source looks like:

1.  For a point source make a custom DiracKernel.  Every time the DiracKernel is applied you get to specify _where_ it's applied.

2.  For a distributed source (like a gaussian that's going to span many elements) you could use a parsed function and UserForcingFunction... or you could write your own Kernel.
