Radial heat source in 2-D #88
Description
When using the radial heat source in 2-D, it is possible that none of the radial lines of laser rays hits the 2-D geometry.
It should be possible to ensure the rays align with the 2-D plane for 2-D cases.
Disabling the radial heat source is a work around but I am leaving this issue here so we don't forget.
