RepeatCurrentTimeStep

repeat the current time step with different parameters or reduced pointcloud

Repeat the current time step with

the same pointcloud, but with changes in the simulation parameters, see %RepeatCurrentTimeStep_BasedOnSamePointCloud% and RepeatCurrentTimeStep_ChangeCVconfiguration
a reduced pointcloud, see %RepeatCurrentTimeStep_BasedOnReducedPointCloud%. Optionally, also here the simulation parameters can be changed.

MESHFREE creates a copy of the current pointcloud, does a time step, and deletes the pointcloud again. The only way to save data from the repeated time step is by RepeatCurrentTimeStep_SaveVariables . Finally, there is the chance to also initialize parameters of the temporary pointcloud by the original one, see RepeatCurrentTimeStep_InitializeVariables .
