get_pdfEq_d3q19 Function

private pure function get_pdfEq_d3q19(rho, vel, QQ, cxDirRK, weight) result(fEq)

This function computes the equilibrium pdf from velocity

Arguments

Type	Intent	Optional	Attributes		Name
real(kind=rk),	intent(in)			::	rho	density
real(kind=rk),	intent(in)			::	vel(3)	velocity
integer,	intent(in)			::	QQ	size of the pdf
real(kind=rk),	intent(in),	optional		::	cxDirRK(:,:)	velocity streaming normal along iDir
real(kind=rk),	intent(in),	optional		::	weight(:)	weight along iDir

Return Value real(kind=rk), (QQ)

output is equilibrium pdf
