Accessing workspace variables with parallel workers
I have a simulink model that I would like to run a number of times over a range of 2 different variables. In my simulink model I was using model callbacks to take the 2 random initial variables and calculate the initial conditions to some of my integrators but this wasn’t working and now I am doing this in the for loops. However when I run the simulation it throws an error saying "Warning: Error in the simulation was caused by missing variable ‘q_e2b0’. Set "TransferBaseWorkspaceVariables" option to "on" to fix the issue." I tried setting that in setModelParameters but that doesn’t work either.
Below is a pseduo code of my script:
num_sims = length(phi_range)*length(theta_range);
simIn(1:num_sims) = Simulink.SimulationInput(‘SixDOFSimulink’);
sim_itr = 1;
for i = 1:length(phi_range)
for j = 1:length(theta_range)
phi0 = phi_range(i);
theta0 = theta_range(j);
% do calculations %
pos0 = %value%
v_b0 = %value%
w0 = %value%
q_e2b_0 = %value%
simIn(sim_itr) = simIn(sim_itr).setModelParameter(‘SimulationMode’, ‘normal’, …
‘SaveTime’, ‘on’, …
‘SaveOutput’, ‘on’);
simIn(sim_itr) = simIn(sim_itr).setVariable(‘theta0’, theta0, ‘workspace’, ‘SixDOFSimulink’);
simIn(sim_itr) = simIn(sim_itr).setVariable(‘phi0’, phi0, ‘workspace’, ‘SixDOFSimunlink’);
simIn(sim_itr) = simIn(sim_itr).setVariable(‘q_e2b0’, q_e2b0, ‘workspace’, ‘SixDOFSimunlink’);
simIn(sim_itr) = simIn(sim_itr).setVariable(‘v_b0’, v_b0, ‘workspace’, ‘SixDOFSimunlink’);
simIn(sim_itr) = simIn(sim_itr).setVariable(‘pos0’, pos0, ‘workspace’, ‘SixDOFSimunlink’);
simIn(sim_itr) = simIn(sim_itr).setVariable(‘w0’, w0, ‘workspace’, ‘SixDOFSimunlink’);
sim_itr = sim_itr+1;
end
end
out = parsim(simIn, ‘ShowProgress’, ‘on’);
