u/erica/2D_Godunov
v18 v19 9 9 This method begins by initializing a 2D Cartesian grid, with a circle in the center. The primitive fluid variables (rho, xvelocity, yvelocity, pressure) are set inside and outside of this circle. 10 10 11 Here are some 3D plots of the initial condition. The x and y axisis the spatial domain, and the zaxis is the value of the fluid variable. You will see a circle of high density/pressure in the center of the mesh, with zero velocity in both x and y.11 Here are some 3D plots of the initial condition. The xy plane is the spatial domain, and the zaxis is the value of the fluid variable. You will see a circle of high density/pressure in the center of the mesh, with zero velocity in both x and y. 12 12 13 13 Density (pressure looks similar):
