Script Implementation

The script used (okc_to_curve.sh) can be found in the attachments below, along with the original sink file for frame 0 and its three projections. To run the script, copy it into your run directory with the .okc files and execute it. Immediately new curve files should be produced. With this method we simply plot the sinks as a curve file instead of as a pseudocolor variable inherent in the chombo (pmass).

To execute: Run the script (i.e. sh okc_to_curve.sh or bash okc_to_curve.sh, on a super computer that uses slurm one could even use sbatch okc_to_curve.sh and it will run instantaneously.) Now you'll have files for each sink_*.okc that are of the form sink_*.okc.xy.curve, .okc.yz.curve, and .okc.zx.curve. We will be visualizing these three curve files that are produced by the script.

Visualizing Sink Curves

1. Import and visualize the data you want to see your sinks projected on. In Figure 1 we are looking at a (Add + > Pseudocolor > mass1) a mass1 bov, which integrates the density over time down the barrel of a colliding flow problem (this particular problem is beta 10, shear 15). Thus we are going to want to project the sinks_*.okc.yz.curve as it corresponds to the same axis as mass1.

Figure 1. Imported our data set to VisIt that we want to use our sink curve on.

2. Import your .curve files through Add + > Curve > curve. Note the new database correlation created in Figure 2. If you want to order them similarly to mass1, mass2 and mass3 — then proceed with yz (x-axis, i.e. mass1), zx (y-axis, i.e. mass2), and xy (z-axis, i.e. mass3).

Figure 2. Imported curve file. Note the new database correlation.

3. Now we need to edit the attributes of our curve data in order to see it.

Figure 3. What one is confronted with when initially opening the attributes. Choose a color that does not conflict with the color bar of your data. Here we choose black. Feel free to tick off the legend and labels in order to make a neater window space.

Figure 4. Under geometry we tick off 'show lines' and tick on 'show points' given we are clearing with data in the form of x-y coordinates. We choose to denote the illustration of these points on the bov as small axes.
