1D MAC FDM Fixed Inlet
G'day people.
I want to solve 1D viscid Euler set of equation.Flow is through a pipe, and all the paramaters ( rho, v,T) are fixed at the inlet boundary. questions: 1-does fixing all parameters cause instability? 2-what is the best practice for time step size? |
Re: 1D MAC FDM Fixed Inlet
I still need help about that maccormac's technique.
I selected the density to be float and others to ve fixed. Although time steps are very small(0.001 s for grid size 0.1m)i have crash after 15~16th time step. Helpppppppppppppppp Hilfeeeeeeeeeeeeeeee thanks |
