Hi,
I'm trying to create a non-ideal flowmeter (i.e. pressure drop different from 0) using simscape component block and modifying slightly the "hydraulic flow rate sensor" block's source data. For that, I've calculated the pressure losses outside and included them as an input (P_loss). However, when I run the model, it stays in the first moments and I have to stop it manually. Does anybody know the reason? I've also tried to use cell arrays indexing and value and cell2mat functions to equalize P_loss and p but matlab does not permit these actions in "equations blocks". Here is the .ssc file:
component nonideal_flowmeter
inputs
P_loss = {0, 'Pa'}; % P_loss:left
end
nodes
A = foundation.hydraulic.hydraulic; % A:left
B = foundation.hydraulic.hydraulic; % B:right
end
variables
q = {1e-3, 'm^3/s'}; % Flow rate
p = {0, 'Pa'}; % Pressure differential
end
branches
q : A.q -> B.q;
end
equations
p == A.p - B.p;
p == P_loss;
end
end
