Simulation setup
To simulate FMU `CoupledClutches.fmu` with OMSimulator run ```bash $ wine64 /var/lib/jenkins/ws/Sandbox/Andreas/OMSimulator-FMI-Cross-Check/OMSimulatorBinaries/OMSimulator-mingw64/bin/OMSimulator.exe --stripRoot=true --skipCSVHeader=true --addParametersToCSV=true --suppressPath=true --timeout=60 CoupledClutches.lua ``` Lua file: ```lua -- Lua file for CoupledClutches.fmu oms_setTempDirectory("/tmp/cross-check") oms_newModel("model") oms_addSystem("model.root", oms_system_sc) -- instantiate FMU oms_addSubModel("model.root.fmu", "CoupledClutches.fmu") -- Simulation settings oms_setResultFile("model", "CoupledClutches_out.csv") oms_setStartTime("model", 0.0) oms_setStopTime("model", 1.5) oms_setTolerance("model", 1e-08, 0.0001) oms_setVariableStepSize("model", 1e-12, 1e-12, 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.
