Data Types
type	coefs::coef_t
	Coefficients defined on a given (mesh, \( X_h \)) tuple. Arrays use indices (i,j,k,e): element e, local coordinate (i,j,k). More...

Modules
module	coefs
	Coefficients.

Functions/Subroutines
subroutine	coefs::coef_init_empty (this, xh, msh)
	Initialize empty coefs for a space and a mesh.
subroutine	coefs::coef_init_all (this, gs_h, scope)
	Initialize coefficients.
subroutine	coefs::coef_free (this)
	Deallocate coefficients.
subroutine	coefs::coef_release_scratch (this)
	Release the coefficients that COEF_OPERATOR does not retain.
subroutine	coefs::coef_generate_dxyzdrst (c)
subroutine	coefs::coef_generate_geo (c)
	Generate geometric data for the given mesh.
subroutine	coefs::coef_metric_condition (this)
	Compute the largest condition number of the metric tensor over the mesh.
subroutine	coefs::coef_generate_geo_compressed (c)
	Compute processor-local compressed versions of mappings Gij.
subroutine	coefs::coef_generate_mass (c)
	Generate mass matrix B for the given mesh and space.
subroutine	coefs::coef_require_facets (this, who)
	Abort unless this coef holds the facet areas and normals.
pure real(kind=rp) function, dimension(3)	coefs::coef_get_normal (this, i, j, k, e, facet)
	Facet normal at a point.
pure real(kind=rp) function	coefs::coef_get_area (this, i, j, k, e, facet)
	Facet area at a point.
subroutine	coefs::coef_generate_area_and_normal (coef)
	Generate facet area and surface normals.
subroutine	coefs::coef_generate_cyclic_bc (this)
subroutine	coefs::coef_recompute_metrics (this)
	Recompute and update geometric factors (ALE)
subroutine	coefs::coef_enable_lagged_mass (this)
	Enable separate memory for lagged B matrices if needed. For eg. when mesh moves.
subroutine	coefs::coef_update_lagged_mass (this)
	Update history: Blaglag = Blag, Blag = B.

Variables
real(kind=rp), parameter, public	coefs::neko_metric_cond_sp = 1.0e4_rp
	Largest metric condition number for which single precision storage of the geometric factors \( G_{ij} \) is considered safe.
integer, parameter, public	coefs::coef_full = 0
	Retain every coefficient. The default, and the only scope that supports recompute_metrics(), generate_cyclic_bc(), get_area(), get_normal() and any consumer of jac, jacinv, Binv or the derivative arrays.
integer, parameter, public	coefs::coef_operator = 1
	Retain only what applying a discrete operator needs: \( G_{ij} \), h1, h2, B and mult.
