vef

Synonyms: vefprep1b

Inherits from: discretisation_base

Finite element volume discretization (P1NC/P1-bubble element). Since the 1.5.5 version, several new discretizations are available thanks to the optional keyword Read. By default, the VEFPreP1B keyword is equivalent to the former VEFPreP1B formulation (v1.5.4 and sooner). P0P1 (if used with the strong formulation for imposed pressure boundary) is equivalent to VEFPreP1B but the convergence is slower. VEFPreP1B dis is equivalent to VEFPreP1B dis Read dis { P0 P1 Changement_de_base_P1Bulle 1 Cl_pression_sommet_faible 0 }

Parameters:

[changement_de_base_p1bulle] (type: int into [0, 1]) changement_de_base_p1bulle 1 This option may be used to have the P1NC/P0P1 formulation (value set to 0) or the P1NC/P1Bulle formulation (value set to 1, the default).
[p0] (type: flag) Pressure nodes are added on element centres
[p1] (type: flag) Pressure nodes are added on vertices
[pa] (type: flag) Only available in 3D, pressure nodes are added on bones
[rt] (type: flag) For P1NCP1B (in TrioCFD)
[modif_div_face_dirichlet] (type: int into [0, 1]) This option (by default 0) is used to extend control volumes for the momentum equation.
[cl_pression_sommet_faible] (type: int into [0, 1]) This option is used to specify a strong formulation (value set to 0, the default) or a weak formulation (value set to 1) for an imposed pressure boundary condition. The first formulation converges quicker and is stable in general cases. The second formulation should be used if there are several outlet boundaries with Neumann condition (see Ecoulement_Neumann test case for example).
[reorder] (type: reorder_mesh) Reordering directive.
