The principal features of this version v5p3 of TELEMAC-3D are:

• An option with prisms split into tetrahedrons.
• A new way of solving the diffusion step.

Character string. The default value is “PRISM”

Two choices are now possible:

PRISME OR PRISM : classical option.

TETRAEDRE OR TETRAHEDRON : prisms split into tetrahedrons.

Integer. The default value is OPTDIF = 1

Two choices are currently possible:

OPTDIF = 1 : implicit diffusion (classical option) .

OPTDIF = 2 : implicitation of the diagonal term of the diffusion with the coefficient TETADI for all variables. In this case, all « Maximum number of iterations for diffusion » have to be set : current value is 1

Double precision. The default value is TETADI = 1.5

Activated only if the keyword value OPTION FOR THE DIFFUSION = 2

None
