Simulation setup
To simulate FMU `CoupledClutches.fmu` with OMSimulator run ```bash $ /var/lib/jenkins2/ws/Sandbox/Andreas/OMSimulator-FMI-Cross-Check/OMSimulatorBinaries/OMSimulator-linux-amd64/bin/OMSimulator --stripRoot=true --skipCSVHeader=true --addParametersToCSV=true --intervals=500 --suppressPath=true --timeout=60 CoupledClutches.lua ``` Lua file: ```lua -- Lua file for CoupledClutches.fmu oms_setTempDirectory("temp") oms_newModel("model") oms_addSystem("model.root", oms_system_sc) -- instantiate FMU oms_addSubModel("model.root.fmu", "../../../../../../../../../fmus/2.0/me/linux64/MapleSim/2016.2/CoupledClutches/CoupledClutches.fmu") -- Simulation settings oms_setSignalFilter("model", ".*") oms_setResultFile("model", "CoupledClutches_out.csv") oms_setStartTime("model", 0.0) oms_setStopTime("model", 1.5) oms_setTolerance("model", 1e-05) initialStepSize, minimumStepSize, maximumStepSize, status = oms_getVariableStepSize("model") oms_setVariableStepSize("model", 0.003, minimumStepSize, 0.003) oms_setFixedStepSize("model", 0.003) -- Instantiate, initialize and simulate oms_instantiate("model") oms_initialize("model") oms_simulate("model") oms_terminate("model") oms_delete("model") ``` See the [OMSimulator documentation](https://openmodelica.org/doc/OMSimulator/master/html/index.html) for more information.
