Laser line has zero length ## ignored
Laser lines imported by *LSRF or generated using *LSRP which have zero, or close to zero laser length, will not be processed by the solver.
More than one heat source detected operating simultaneously. If this is not a multi-laser system check the .lsr file for errors.
This critical warning occurs when 2 or more simultaneous heat sources are active. If this was not the design intent, fix the .lsr file.
