MapleSim Hydraulics Library from Modelon

command_diameter_4_3_B  Interface for geometry calculation for a 4-port, 2- or 3-position spool

Class used to calculate the commanded diameter for the Spool 4 3 B component.

Events

There is a new boolean reduceEvents (selected by default) in the Parameters  Advanced section under the Inspector tab. Selecting reduceEvents lets the model use noEvents(expr) to generate fewer events for boolean expressions that should not generate events. In some cases the solver might reduce the stepsize too much and generate a lot of steps. If this happens, try clearing reduceEvents.
