I am trying to simulate a simple circuit with simulink, but it occurs error 'Initial conditions solve failed to converge' persistingly. Please refer to files I attached and help me solve this problem. The goal of this simulation is to obtain 3 figures as 'simulink result'.
I tried this simulation in MATLAB code and it was successful, but I still have a problem in simulink simulation
MAIN code
function Test clear all L1=0.1; L2=0.2; L3=0.1; R1=1; R2=2; R3=1; C=1e-6; V=10; R=[-R1 0 0;0 -(R2+R3) -1;0 1 0]; D=[1;0;0]; L=[(L1+L3) -L3 0;-L3 (L2+L3) 0;0 0 C]; A=inv(L)*R; B=inv(L)*D; X=[0;0;0]; U=V; T=0.00005;
for n=1:20000 n1(n)=n; X1=X; term1=A*X1+B*U; X2=X1+T*(A*X1+B*U); term2=A*X2+B*U; X=X+(T/2)*(term1+term2); i1(n)=X(1); i2(n)=X(2); Vc(n)=X(3); end
time=n1*T;
