| cme-n0.mpg | A movie showing the first Sun-related simulation run: A 3D-density 'disturbance' expands outwards. Timescale is dt = RSun / vSound = 40 min, corresponding to T = 4 x 106 K. |
| cme-nv.mpg | Same as above, this time also showing fluid velocity as arrow field. |
| awings-v.mpg awings-p.mpg awings-b.mpg | Three animations showing the rise of Alfven wings emanating from an spherical obstacle embedded in a magnetized fluid flow in contours of velocity (v), plasma pressure (p), and as magnetic field lines (b). Wedges in the last frame indicate the wing direction as expected from theory. For a more detailed explanation see summary talk by JK (above). |
| sedov3d.mpg | 3D contour plot of a sedov explosion simulated using adaptive mesh refinement. Was done as a test run and published in a joint CPC paper. |
| rvp-cube.mpg | A three-dimensional visualization of solution paths in (r,v,p) space for a non-isothermal HD wind |
| V_LTcme80-90deg-8.mpg lN_LTcme80-90deg-8.mpg B_LTcme80-90deg-8.mpg | MHD solar wind run showing convergence to stationary state (after a rather violent relaxation from an artificial and thus somewhat unphysical initial conditon). At t=8, an equatorial disturbance is launched via changing initial condition at the solar boundary. Shown: Velocity contours, logarithmic mass density, and magnetic field lines, respectively. Grid resolution is 803 grid points, all movies represent cuts along the poloidal plane. |
