MIN substeps
Here you can define the minimum number of time steps that will be used for a simulation.
If you need more precision, it is sometimes better to raise “MIN substeps” than to alter the maximum number.
In some cases it can even be necessary to use a “MIN substeps” that is very close to “MAX substeps”.
Fixed time steps can be achieved by using the same values for both “MIN substeps” and “MAX substeps”.
