fluid_stats Module Reference

Computes various statistics for the fluid fields. We use the Reynolds decomposition for a field u = + u' = U + u' Spatial derivatives i.e. du/dx we denote dudx.

Data Types
type	fluid_stats_t

Functions/Subroutines
subroutine	fluid_stats_init (this, coef, u, v, w, p, set)
	Constructor. Initialize the fields associated with fluid_stats.
subroutine	fluid_stats_update (this, k)
	Updates all fields with a new sample.
subroutine	fluid_stats_free (this)
	Destructor.
subroutine	fluid_stats_reset (this)
	Resets all the computed means values and sampling times to zero.
subroutine	fluid_stats_make_strong_grad (this)
subroutine	fluid_stats_post_process (this, mean, reynolds, pressure_flatness, pressure_skewness, skewness_tensor, mean_vel_grad, dissipation_tensor)
	Compute certain physical statistical quantities based on existing mean fields.
