FunctionPathEllipsoidHeatSource

Double ellipsoid volumetric source heat with function path.

Description

This is a material for generating a moving heat source with an ellipsoidal shape that follows a user-defined path, with the volumetric heat source being defined as follows:

where:
- is the power
- is the efficiency
- is the scaling factor
- , , and are the effective heating spot radii in three directions
- , , are the heating spot travel path in three directions

This material property is designed to model the heat generated by a laser beam during an additive manufacturing process, which should be applicable to heat sources that have similar characteristics. Note, this is used together with the ADMatHeatSource.
