I am having the following error with plotting :
Index exceeds the number of array elements (104).
Error in MUSCL_main (line 144)
plot(Ini_x,history(h).U_Euler(1,:))
The code:
Nodes = 120;
cells = Nodes-1;
Ghost = 2;
Ini_x = Cells+2*Ghost;
U_Euler = zeros(8,Ini_x);
end_time = 6.0;
t= 0;
[dt_E] = DT(U_Euler, CFL, dx, 0);
n=0;
h=1;
while (t < end_time)
for k = 1:4
[U_Le, U_Re] = MUSCL(U_Le, U_Re , U_RK_Euler);
V_EulerL = switch_Con2Prim(U_Le, Gamma, mu_0, 0);
[Flux_E] = computeFluxes(Flux_E, V_EulerL, V_EulerR, U_Le,U_Re,dt_E,dx, 0);
[Res_E] = Residual(Flux_E, dx, dy, dz, Res_E);
[U_RKe] = RK4( U_Euler, dx, dy, dz, dt_E, k);
U_RK_Euler = Boundary_periodic(U_RKe);
end
U_Euler = U_RK_Euler;
t = t+dt_E;
if mod(n,10)== 0
history(h).U_Euler = U_Euler;
h=h+1;
end
n=n+1;
end
plot(Ini_x,history(h).U_Euler(1,:)) % error
I am trying to plot the data saved in the "history"
