Motor-Cad wont export results as .csv file (or any other file type)

Hi guys,

I am trying to run an automated motor-cad script, but when I try to export the results to a .csv file I get the following error:

"Error using COM.MotorCAD_AppAutomation/ExportResults

Invoke Error, Dispatch Exception:

Source: MotorCAD.AppAutomation

Description: Range check error"

The computation runs succesfully, and I get reults with the "GetVariable" method.

My Code is pretty much the default example:

%% Script initialisation
% Launch Motor-CAD
mcad = actxserver('MotorCAD.AppAutomation');
% Disable all popup messages
invoke(mcad,'SetVariable','MessageDisplayState',2);
% Choose model type
invoke(mcad,'ShowMagneticContext');

%% Geometry
% Display the scripting tab
invoke(mcad,'DisplayScreen','Scripting');
invoke(mcad,'LoadFromFile','C:\NotrealPath')

% Set the slot number, tooth width and magnetic thickness
% invoke(mcad,'SetVariable','Slot_Number',24);
% invoke(mcad,'SetVariable','Tooth_Width',6);
% invoke(mcad,'SetVariable','Magnet_Thickness',4.5);

%% Custom Winding Example
%{
% Set the number of phases, parallel paths and winding layers:
invoke(mcad,'SetVariable','MagPhases',3);
invoke(mcad,'SetVariable','ParallelPaths',1);
invoke(mcad,'SetVariable','WindingLayers',2);
% Set the winding type to custom
invoke(mcad,'SetVariable','MagWindingType',1);
% Set the Path type to Upper and Lower
invoke(mcad,'SetVariable','MagPathType',1);
% Define a coil's parameters:
% Phase, Path, Coil, Goslot, GoPosition, ReturnSlot, ReturnPoisition, Turns
% Position parameters can be "a", "b", "c" etc. for Upper/Lower paths and "L" or "R" for Left/Right paths
invoke(mcad,'SetWindingCoil',2, 1, 3, 4, 'b', 18, 'a', 60);
%}
%% Materials
% Change the stator/rotor lamination materials
% invoke(mcad,'SetComponentMaterial','Stator Lam (Back Iron)','M250-35A');
% invoke(mcad,'SetComponentMaterial','Rotor Lam (Back Iron)','M250-35A');

%% Calculation Options
% Run a transient torque calculation with 30 points in 1 electrical cycle
PointsPerCycle = 3;
NumberCycles = 1;
invoke(mcad,'SetVariable','TorquePointsPerCycle',PointsPerCycle);
invoke(mcad,'SetVariable','TorqueNumberCycles',NumberCycles);

% Disable all performance tests except for the torque calculation in order
% to minimise simulation time
invoke(mcad, 'SetVariable', 'BackEMFCalculation', false);
invoke(mcad, 'SetVariable', 'CoggingTorqueCalculation', false);
invoke(mcad, 'SetVariable', 'ElectromagneticForcesCalc_OC', false);
invoke(mcad, 'SetVariable', 'TorqueSpeedCalculation', false);
invoke(mcad, 'SetVariable', 'DemagnetizationCalc', false);
invoke(mcad, 'SetVariable', 'ElectromagneticForcesCalc_Load', false);
invoke(mcad, 'SetVariable', 'InductanceCalc', false);
invoke(mcad, 'SetVariable', 'BPMShortCircuitCalc', false);
invoke(mcad, 'SetVariable', 'TorqueCalculation', true);

%% Operating Point
% Set the operating point of the machine - speed, current and phase
% advantage
invoke(mcad, 'SetVariable', 'Shaft_Speed_[RPM]', 1000);
invoke(mcad, 'SetVariable', 'CurrentDefinition', 0);
invoke(mcad, 'SetVariable', 'PeakCurrent', 3); 
invoke(mcad, 'SetVariable', 'DCBusVoltage', 350);
invoke(mcad, 'SetVariable', 'PhaseAdvance', 45);

%% Saving File
% invoke(mcad,'SaveToFile','C:\Workspace\ActiveX_Scripting_EMagnetic.mot');

%% Simulation
success = invoke(mcad,'DoMagneticCalculation');
if success == 0
    disp('Magnetic calculation successfully completed');
else
    disp('Magnetic calculation failed');
end

%% Results
% Export data to csv file
success = invoke(mcad,'ExportResults','EMagnetic','D:\ANSYS_Motor-CAD\14_1_4\Emag\Export EMag Results.csv');
if success == 0
    disp('Results successfully exported');
else
    disp('Results failed to export');
end

% Output Data Sheets
[success,ShaftTorque] = invoke(mcad,'GetVariable','ShaftTorque');
[success,LineVoltage] = invoke(mcad,'GetVariable','PeakLineLineVoltage');

I have met the same problem like you. How did you solve it finally?

Copied file, renamed it, chose a different lokal path.

Thanks, Dom. I will give it a try.
