Basic Settings

surface meshing tolerance: Determines the relative size at which small cells from a meshed geometry surface are dropped. Set to 1.0 for simulations that do not contain any geometries.

cfl number: If time step is set to zero, the time step is automatically calculated, and for EM simulations, is reduced proportionately with the cfl number. The cfl number is the ratio of time step to Courant limit.

time step: If set to a value that is non-zero, this will be used as the simulation time step. If set to zero, the time step is calculated for you based on a number of factors.

• If it is an ES simulation without particles, the time step is set to 1.0.
