Sets the quality of the simulation by balancing the Substeps value in the Lagoa Simulate Multiphysics node and the Resolution data set in the Emit node.
Resolution is the size and number of points per unit (space quality).
Substeps is the simulation accuracy as it evolves in time (time quality).
This node prevents you from using too many or too few substeps. It should give you an approximated optimal number of substeps for the given resolution.
Plug this compound's Substeps output into the Substeps port of the Lagoa Simulate Multiphysics node.
You can also select a point cloud and choose Particles 
On Emission Lagoa Particles Lagoa Resolution to Substeps from the ICE toolbar to have this node set up in the point cloud's ICE tree.
