d(pv)/dx+dp/dt=0
d(pv^2)/dx+d(pv)/dt+R*T_a*dp/dx=0
with initial condition
p(x,0)=p_a
v(x,0)=0
and boundary condition
p(L,t)=p_a
p(0,t)=if t<t_s then p_a else p_r
v(0,t)=if t<t_s then 0
here in the attachment you see what I have made so far. But I get errors when I solve:
Error
The following features has encountered a problem
-Feature Time-Dependent Solver 1 (sol1/t1)
Repeated error test failures. May have reached a singularity. Time 0.5137664504948306
Last time step is not converged
I would appreciate if you could help me sort this issue out.
P.S.
1. for some reason I'm not able to attach a file here so I uploaded the file somewhere else:
