Name

gf_eltm — get a descriptor

Calling Sequence

ELTM = gf_eltm(elt_matrix_type, args..)

Description

  • gf_eltm('base', Fem FEM) return a descriptor for the integration of shape functions on elements, using the Fem FEM.

  • gf_eltm('grad', Fem FEM) return a descriptor for the integration of the gradient of shape functions on elements, using the Fem FEM.

  • gf_eltm('hessian', Fem FEM) return a descriptor for the integration of the hessian of shape functions on elements, using the Fem FEM.

  • gf_eltm('normal') return a descriptor for the unit normal of convex faces.

  • gf_eltm('grad_geotrans') return a descriptor to the gradient matrix of the geometric transformation.

  • gf_eltm('grad_geotrans_inv') return a descriptor to the inverse of the gradient matrix of the geometric transformation (this is rarely used).

  • gf_eltm('product', Eltm A, Eltm B) return a descriptor for the integration of the tensorial product of elementary matrices A and B. In order to obtain a numerical value of theses matrices, see gf_mesh_im_get(MIM,('eltm').
