[run_id].diag what are the headers for this data? #185

Open speed-wagon opened 4 years ago

speed-wagon commented 4 years ago

The diagnostic file contains some good data regarding the simulation. However the file contains some 30 columns. Whilst I am able to guess some of the values like the time step, time and dt...it would be nice to now exactly what all the headers were.

I havent been able to locate any info on this in the docs and looking into the source code has only lead me to find ~20 of the 30 column headers.

Can anyone help with this?

Is what you are looking for in the function: void Simulation::RecordDiagnostics(void)

in https://github.com/gandalfcode/gandalf/blob/master/src/Common/SimAnalysis.hpp

That is the function were I obtained the first 20 or so headers, but my .diag file contains 30 columns.

The simlation is the accretion disk. Unsure if this adds addional simulation specific columns

The lines

for (k=0; k<3; k++) outfile << diag.angmom[k]*simunits.angmom.outscale << "     ";
  for (k=0; k<ndim; k++) outfile << diag.rcom[k]*simunits.r.outscale << "     ";
  for (k=0; k<ndim; k++) outfile << diag.vcom[k]*simunits.v.outscale << "     ";
  for (k=0; k<ndim; k++) outfile << diag.mom[k]*simunits.mom.outscale << "     ";
  for (k=0; k<ndim; k++) outfile << diag.force[k] << "     "; //*simunits.f.o

Output 3 items each for a 3D simulation.
