v31 v32 78 78 Tracer variables are used to track the movement of specific quantities of matter within your simulation. If, for instance, you had one or more clumps suspended in an ambient medium and wanted to track the way the clump matter moves through the domain, you would use a tracer. 79 79 80 '''Note:''' Certain aspects of tracer behavior are controlled by the {{{iTracerParameter}}} in [SolverDataExplained solver.data]. However, the parameter below is used to activate tracers in the simulation. 81 80 82 * '''''{{{NrTracerVars:}}}''''' Indicates the number of tracer variables to use in this problem. If {{{NrTracerVars}}} is {{{0}}}, then tracers will not be active. Tracking tracer variables costs memory and CPU cycles, so it's best to leave this switched off if you don't anticipate needing them. Under no circumstances should {{{NrTracerVars}}} be less than 0. 81 83 [[BR]]
