Visualizing AWP-ODC Output

This page documents a procedure to visualize AWP-ODC velocity output, using remote Paraview. So far, this procedure has only been tested on Titan using Paraview 4.4.0.

Configure the simulation

When running the AWP-ODC simulation, make sure it is configured to produce velocity output.

Take note of the following parameters:

• NX, NY, NZ (and NBGX, NEDX, NGBY, NEDY, NGBZ, NEDZ if specified)
• WRITE_STEP
• NSKPX, NSKPY, NSKPZ
• NTISKP

They'll be needed when producing the output.

Create a Paraview XDMF file

Once the simulation is complete, we must create a configuration file which tells Paraview how the velocity data is laid out in memory.

For this, run the script create_timeseries_file.py.

Usage: ./create_timeseries_file.py <X dim in output> <Y dim in output> <grid decimation> <NT in sim> <DT of sim> <NTISKP> <timesteps output per file> <prefix> <output file>

Based on this, a XDMF (XML) file is produced which can serve as input to Paraview.
