How do I get a kspaceFirstOrder2D analysis to operate over an arbitrarily long time period. I see that kgrid has two properties t_array, Nt and dt but how do I set these properties so that the analysis proceeds over a longer time period than provided by default?
Thanks for your help and a great/interesting toolbox!
Hi Ian,
There are a couple of possibilities. First, you can set kgrid.t_array manually after calling makeGrid but before running the simulation. For example:
dt = 1e-9;
t_end = 1e-6;
kgrid.t_array = 0:dt:t_end;Second, you can call the function makeTime to create the time array for you. This has parameter inputs to set the CFL number and the end time. For example:
kgrid.t_array = makeTime(kgrid, medium.sound_speed, cfl, t_end)
The other parameters, kgrid.Nt and kgrid.dt are automatically derived from kgrid.t_array (they shouldn't be modified directly).
Good luck with your simulations,
Brad.
