Monte Carlo Settings dialog box (Thermal/SST/ESC/Multiphysics)

Option Description
Name Specify a meaningful name for the modeling object.
Label Specify a unique numeric identifier for the modeling object.
Description Specify a description for the modeling object.
Settings
Calculate View Factors Only Calculates view factors using the Monte Carlo method. The thermal solver uses the computed view factors to determine radiative fluxes and conductances.If you deselect this option, the solver uses the Monte Carlo method for the direct calculation of radiative coupling and radiative fluxes by continuing to trace all rays to their extinction. View factors are not computed.
Ray Density Control Specifies the method used to control the density of randomly generated rays launched from each element.Rays per ElementLaunches the specified number of rays from each element.Rays per AreaLaunches the specified number of rays from the averaged element area.Based on Error CriterionLaunches more and more rays until the specified Error Criterion is satisfied to a Confidence Level (%) you specify.
Random Number Generator Controls the generation of random rays.AutomaticUses a standard random number generator.Specify SeedAllows you to specify a Seed Value to the random number generation algorithm.
