This refers to the setup of the detectors in the optimization simulation.
Generally, it is sensible to set the ray casting parameters to be the ones that you wish to use in the final simulation. For complex cases, it may be necessary to reduce the resolution of the rays in order to reduce computation time. However, it may be the case that the coverage is slightly lower in the project once the detectors are added and set to a finer ray casting resolution. In other words, the coverage in the optimization simulation may be 90.1% 1ooN with 2 degrees resolution and 0 refinements, but when added to the project, if 1 degree resolution and 2 refinements are used, the coverage may decrease to 89.9% 1ooN (See the Detect3D Calculation Theory Guide for more information about resolutions and refinements of flame detectors).
It may be prudent to slightly increase the target criteria but 0.2-0.5% if coarser resolution is used. Another tactic could be to change the resolution while the simulation is running, i.e. get through the majority of the simulation using coarse resolution and increase to finer resolution at the end.
The number of adaptive refinements used for the ray casting calculations for all detectors (including those defined in the initial setup). This setting can be changed while the simulation is running.
The default is set to a value of 2.
The angular resolution of the rays for all detectors (including those defined in the initial setup). This setting can be changed while the simulation is running.
The default is set to a value of 1.
The flame detector model used for detectors added to an initial layout. The detectors in the initial layout always use the flame detector model that they were originally assigned. This setting can be changed while the simulation is running.
