WSMSimulationData

WSMSimulationData[...]
represents Modelica simulation data.
MORE INFORMATION
  • In standard output format, only the simulation interval and the number of variables in a object are printed explicitly.
  • gives a list of possible properties.
  • Properties of simulation data are obtained from .
  • Properties of the simulated model:
"VariableNames"dependent variables in the model
"ParameterNames"parameter variables in the model
"ModelName"fully qualified name of the model
  • Properties specific to the simulation:
"SimulationInterval"simulation interval
"NumberOfEvents"number of events in the simulation
  • For simulations with animation information, returns a Graphics3D at time t.
  • Properties related to values of variables and parameters:
{"v1","v2",...}simulation for , , ...
{"p1","p2",...}parameter value for , , ...
  • Simulation results for variables are returned as functions that can be evaluated for any time t.
  • Simulation results from object sd can be evaluated at a point t with .
  • Complete lists of simulation results and parameter values:
"VariableValues"simulations
"ParameterValues"parameters
  • Lists of simulation results from sd can be evaluated at a point t with .
  • Variables depend on parameters ; the sensitivity of a variable to a parameter is the partial derivative . Sensitivities can be computed using WSMSimulateSensitivity.
  • Sensitivities can be accessed by the property .
  • Properties related to sensitivities include:
"SensitivityNames"variable parameter sensitivities
"SensitivityValues"sensitivities
