Export of data for FEA

[dora (doraxiong)]

Hi everyone,
I want to export the data of the load on the pelvis in a gait.I insert AnyMechOutputFileForceExport in the inversedynamicstudy folder as follows:

AnyBodyStudy InverseDynamicStudy = {
AnyFolder &C3DData=..ModelSetup.C3DFileData ;
AnyFolder &BodyModel=.HumanModel.BodyModel;
#include "Mannequin.any" //// Usually no need to make changes
AnyFolder &EnvironmentModel = Main.EnvironmentModel;
AnyFolder ModelEnvironmentConnection = {
#include "JointsAndDriversOptimized.any" //// Usually no need to make changes
};
Gravity = Main.TrialSpecificData.Gravity;
tStart = Main.ModelSetup.tStart+2Kinematics.ApproxVelAccPerturb;
tEnd = Main.ModelSetup.tEnd-2Kinematics.ApproxVelAccPerturb;
nStep = Main.TrialSpecificData.nStep;
InverseDynamics.Criterion.UpperBoundOnOff=Off;
InitialConditions.MaxIteration = 20000;
Kinematics.MaxIteration = 20000;
AnyMechOutputFileForceExport FE_out =
{
FileName = "file_in/pelvisload.xml";
UseRefFrameOnOff = On;
AnyRefFrame &ref1 =
Main.Studies.HumanModel.BodyModel.Trunk.SegmentsLumbar.PelvisSeg.localrefframe;
AllSegmentsInStudyOnOff = Off;
AnySeg &pelvis = Main.Studies.HumanModel.BodyModel.Trunk.SegmentsLumbar.PelvisSeg;
XMLformatOnOff = On;
};
};

and I run the inversedynamicstudy ,but it emerge an error ,it said as follow:

ERROR(OBJ.FILE1) : 'ObjectName' : Problem with file : 'FileName(LineNo)' : 'Additional explanation'
Explanation:
This message is sent by AnyFile objects or other objects operating on files. This is a generic message that cover several different issues depending on the actual type of file and the situation. An 'additional explanation' will typically accompany the basic part of the message explaining the particular issue. For text files, references may include the line number of the error if applicable.

How can I solve this problem
Thanks
Dora

Hi Dora,

I am not sure this error relates to the code you have added for the Fe_out output, please out-comment this object again and try to reload, i think this will give same error?

The model you load seems to run on kinematics which is loaded, the problem could also be that this file has been corrupted. Please try to run the related kineamtic model, to recreate jointangle file used in this study.

One more thing, the error you get please try to click the blue link to identify where in the code the problem comes from it will take you to the location of the problem.

Best regards
Søren
