resize!(diag, newnum)

Resize the Diagnostic data and time arrays to length newnum.

increment!(diag)
increment!(diags)

Increment the Diagnostic diag, or an array of Diagnostics diags.

savediagnostic(diag, diagname)

Save diagnostics to file, labeled by the string diagname.

saveoutput(out)

Save current output fields for file in out.filename.

saveproblem(prob, filename)

Save certain aspects of a problem timestepper, grid, and params. Functions that are fields in params are not saved.

stepforward!(prob, diags, nsteps)

Step forward prob for nsteps, incrementing diagnostics in the array diags along the way.

stepforward!(prob, nsteps)

Step forward prob for nsteps.

stepforward!(prob)

Step forward the Problem prob for one timestep.

update!(diag)

Update diag with its current value.

ZeroDGrid()

Constructs a placeholder grid object for "0D" problems (in other words, systems of ODEs).
