先把官網上的說明文件放上來：

simulate

simulates a modelica model by generating c code, build it and run the simulation executable. The only required argument is the className, while all others have some default values. simulate(className, [startTime], [stopTime], [numberOfIntervals], [tolerance], [method], [fileNamePrefix], [options], [outputFormat], [variableFilter], [cflags], [simflags]) Example command: simulate(A); 
 

function simulate
  input TypeName className "the class that should simulated"; input Real startTime = "<default>" "the start time of the simulation. <default> = 0.0"; input Real stopTime = 1.0 "the stop time of the simulation. <default> = 1.0"; input Real numberOfIntervals = 500 "number of intervals in the result file. <default> = 500"; input Real tolerance = 1e-6 "tolerance used by the integration method. <default> = 1e-6"; input String method = "<default>" "integration method used for simulation. <default> = dassl"; input String fileNamePrefix = "<default>" "fileNamePrefix. <default> = \"\""; input String options = "<default>" "options. <default> = \"\""; input String outputFormat = "mat" "Format for the result file. <default> = \"mat\""; input String variableFilter = ".*" "Filter for variables that should store in result file. <default> = \".*\""; input String cflags = "<default>" "cflags. <default> = \"\""; input String simflags = "<default>" "simflags. <default> = \"\""; output SimulationResult simulationResults; record SimulationResult String resultFile; String simulationOptions; String messages; Real timeFrontend; Real timeBackend; Real timeSimCode; Real timeTemplates; Real timeCompile; Real timeSimulation; Real timeTotal; end SimulationResult; end simulate;

 

numberOfIntervals根據我的理解，這個引數是指每秒模擬多少次（每秒間隔數），我將其設定為50，發現在csv檔案中每秒也就存放4,5條資料，不太清楚OpenModelica究竟是怎樣的執行機制。
