Modelica CombiTimeTable

"ModelicaCombiTimeTable" has been replaced by "MCTT".

Background

    • Modelica CombiTimeTable ASCII format data files.
    • File format used by Modelica.
    • Exported files can be read by Modelica component "Modelica.Blocks.Sources.CombiTimeTable".

Import & Export

  • Import["file.txt","ModelicaCombiTimeTable"] imports table data from the ASCII file and returns {"n1"->data1,}, where datai are lists of lists.
  • Export["file.txt",data,"ModelicaCombiTimeTable"] writes data in an ASCII file readable by Modelica component "Modelica.Blocks.Sources.CombiTimeTable".

Import Elements

  • Import element:
  • "ModelicaCombiTimeTable" list of rules with {"n1"->datai,}
  • Export data formats:
  • {{"n1",{{t1,v1},},}time-value pairs {ti,vi} for variable names "ni"
    {{"n1",{v1,},}values vi for variable names "ni"
    {{"n1",ts1},}TimeSeries tsi for variable names "ni"
    {{"n1",f1},}samples of functions fi

Options

  • Option for exporting values {v1,}:
  • SamplingPeriod1distance between samples
  • Options for exporting sampled functions fi:
  • SamplingPeriodAutomaticdistance between samples
    "StartTime"0start time for sampling
    "StopTime"Automaticstop time for sampling
