This parameter defines the disk aspect ratioat . It must be used together with [
FlaringIndex->29] to define it everywhere. Defining the disk thickness in a 2D code might seem surprising. It actually means that one initializes the sound speed , since this later is linked to through:
where is the orbital Keplerian speed.
Note that it is possible to override the sound speed profile implied by
FlaringIndex->29] by providing, in the output directory (defined by [
OutputDir->43]), an ASCII file named
soundspeed.datwhich must contain [
Nrad->38] entries that sample the desired sound speed profile at the zone centers. An arbitrary sound speed profile can therefore be used.
