I am facing while using the parsim command for running my simulations on simulink. IN the code below, I am using a nested for loop. I have called all 3 simulation objects as 'in' with different indexing i1, i2 and i3 for the parameters below.
My code on compiling (without using parallel computing) creates a structure called 's' which stores signals in base workspace. However, when using the parsim command, variable 's' is not found.
Part of code :
modelname = 'SEC_final' ;
% parameters to be used in simulink
dist_5thwheel_to_second_axle_sem2_itr = [7.13, 7.63];
dist_front_trailer_to_5thwheel_sem2_itr = [1.368, 1.668];
dist_pin_coupling_to_dolly_centre_itr = [3.3, 3.8, 4.3]; %drawbar length
%size of above parameters
counter1 = length(dist_5thwheel_to_second_axle_sem2_itr);
counter2 = length(dist_front_trailer_to_5thwheel_sem2_itr);
counter3 = length(dist_pin_coupling_to_dolly_centre_itr);
for i1 = 1:1:counter1 %counter for parameter1
in(i1) = Simulink.SimulationInput(modelname); %simulation object 1 for model
in(i1) = setBlockParameter(in(i1), [modelname '/Semitrailer 2'], 'dist_5thwheel_to_second_axle_sem2', num2str(dist_5thwheel_to_second_axle_sem2_itr(i1)));
for i2 = 1:1:counter2 %counter for parameter2
in(i2) = Simulink.SimulationInput(modelname); %simulation object 2 for model
in(i2) = setBlockParameter(in(i2), [modelname '/Semitrailer 2'], 'dist_front_trailer_to_5thwheel_sem2', num2str(dist_front_trailer_to_5thwheel_sem2_itr(i2)));
for i3 = 1:1:counter3
in(i3) = Simulink.SimulationInput(modelname); %simulation object 3 for model
in(i3) = setBlockParameter(in(i3), [modelname '/Semitrailer 2'], 'dist_front_trailer_to_5thwheel_sem2', num2str(dist_front_trailer_to_5thwheel_sem2_itr(i3)));
% assigning the reference parameters in base workspace
assignin('base','tmax',tmax);
assignin('base','dt',dt);
assignin('base','Vx',Vx);
assignin('base','X0',X0);
assignin('base','rdfname',rdfname);
assignin('base','rdfname_inner',rdfname_inner);
assignin('base','steer_input',steer_input);

assignin('base','lookahead_time',lookahead_time);
assignin('base','T_lag',T_lag);
modelname = 'SEC_final';
% sim(modelname,[],simset('DstWorkspace','base')); % command for normal simulation (not using parallel computing)
out_1 = parsim(in, 'ShowProgress', 'on'); %parsim command
evalin('base',['save ..\simresults\',modelname,' s VR dt']) %s is a structure containing many signals from simulation
end
end
end
