WSMRealTimeSimulate

WSMRealTimeSimulate["mmodel"]

launches a simulation of mmodel synchronized with real time.

WSMRealTimeSimulate["mmodel",tmax]

simulates from 0 to tmax.

WSMRealTimeSimulate["mmodel",vars,…]

stores only simulation data for the variables vars.

Details and Options

  • WSMRealTimeSimulate returns a WSMSimulationConnection object.
  • By default, the simulation will continue until stopped.
  • WSMRealTimeSimulate takes the same arguments and options as WSMSimulate, with the following addition:
  • RefreshRate Automaticcommunications per second
  • With Method ->{"opt1"val1,…}, the following opti can be used:
  • "IP"Automaticinterfaces to listen on
    "Port"Automaticport to listen on
    "WriteSimulationData"Falsewrite results to file
  • Possible options for "IP" are:
  • Automaticlisten on local host
    Alllisten on all interfaces
    "ip"listen on ip
  • Possible options for "Port" are:
  • Automaticautomatically choose a port
    portlisten on port
