| 19 | After checking that the disk module compiles and runs without any issues, you can examine the chombo files created by the first run of this module.[[BR]][[BR]] |
| 20 | If you have no experience on visualization tools, the page [https://clover.pas.rochester.edu/trac/astrobear/wiki/VisItBasics VisIt Basics] is a good resource to learn the basics of it.[[BR]][[BR]] |
| 21 | The following image is a density plot of the disk at time ''t=0'', a log scale has been applied to the perpendicular and parallel slices. |

| 25 | Different elements can be recognized in the image above: |
| 26 | - GxBounds: the boundaries of the plot, namely the physical boundaries of the simulation |
| 27 | - Radius: the radius of the disk |
| 28 | - Height: the height of the disk |
| 29 | - Ambient: the blue portion of the plot, it represents the area around the disk |
| 30 | - PointGravity: a point mass located at the center of the disk |
| 31 | |
32 | | '''Note:''' No scaling is applied to the values above |
| 46 | Sometimes it can be useful to change the size of the physical boundaries of the simulation, this can be done by modifying the section below contained in ''global.data'' |
| 47 | {{{ |
| 48 | GxBounds = -10.d0, ! Problem boundaries in computational units. |
| 49 | -10.d0, ! format: (xlower, ylower, zlower, xupper, yupper, zupper) |
| 50 | -10.d0, ! For 2D problems, set zlower and zupper to 0.d0. |
