![]() ![]() I suggest that the API is refined based on use cases so as to permit easy initialization and invocation, without restricting to the xml approach alone.ĭef perform_jra(model_file, ik_file, grf_file, grf_xml, reserve_actuators,Įxternal_loads = opensim.ExternalLoads(model, grf_xml)Įxternal_tExternalLoadsModelKinematicsFileName(ik_file)Įxternal_tLowpassCutoffFrequencyForLoadKinematics(6)Įxternal_loads.printToXML(results_dir + name + '.xml')įorce_set = opensim.ForceSet(model, reserve_actuators)įorce_set.setMemoryOwner(False) # model will be the owner The tools are an important part of the API, especially with the python and java wrappings. This should be handled automatically when the user sets the corresponding input. IK) then the _loadModelAndInput must be set to true, which is not well documented. The additional force set will not be added to the model even if it is specified by setForceSetFiles, because this is performed in the constructor of the tool rather than before the run method.Īnother problem is the motion vs state input. Another problem is the specification of the reserve actuators. So the user can't pass the ExternalLoads object but is restricted to set the path to the. tResultsDir(parameters.resultsDir) įrom a user perspective the tExternalLoads does not work because in the run method of the analyze tool the external forces are created with createExternalLoads tExternalLoadsFileName(tempExternalLoadsXML) let createExternalLoads to handle the creation of the external loads tCoordinatesFileName(parameters.inverseKinematicsMotion) StaticOptimization->setMaxIterations(100) StaticOptimization->setConvergenceCriterion(0.0001) ![]() StaticOptimization->setUseMusclePhysiology(true) ![]() StaticOptimization->setActivationExponent(2) StaticOptimization->setUseModelForceSet(true) Parameters.subjectName + "_external_loads.xml" ĮxternalLoads externalLoads(parameters.model,ĮtExternalLoadsModelKinematicsFileName(ĮtDataFileName(oundReactionForces) ĮtLowpassCutoffFrequencyForLoadKinematics(6) ĮxternalLoads.print(tempExternalLoadsXML) įorceSet forceSet(parameters.model, parameters.reserveActuators) įor (int i = 0 i setStartTime(motion.getFirstTime()) String tempExternalLoadsXML = parameters.resultsDir + ![]()
