11. Modeling I#
It’s the same modeling as C but with FORMULATION =”U_ PSI “.
11.1. Characteristics of modeling#
Pressure-potential formulation \((u,\psi )\) on “AXIS_FLUIDE” elements. The output impedance is defined by a AXIS_FLUI_ABSO model applied (option IMPE_MECA) to the GROUP_MA =” SORTIE “.
Boundary condition:
ONDE_FLUI: (GROUP_MA ='Entry', PRES =1.0)
