I'm trying to run simulation on delaval nozzle 2D. and using Axisymmetric. I want to define the Pressure and temperature at the inlet, pressure at outlet and symmetry on the rotation axis.
So I used the following configuration and the solution diverges after ** iteration with error: "SU2 has diverged. (NaN detected)"
`
% -------------------- COMPRESSIBLE FREE-STREAM DEFINITION --------------------%
% Mach number (non-dimensional, based on the free-stream values)
MACH_NUMBER= 1e-9
% Angle of attack (degrees, only for compressible flows)
AOA= 0.0
% Side-slip angle (degrees, only for compressible flows)
SIDESLIP_ANGLE= 0.0
% Init option to choose between Reynolds (default) or thermodynamics quantities
% for initializing the solution (REYNOLDS, TD_CONDITIONS)
INIT_OPTION= REYNOLDS
% Free-stream option to choose between density and temperature (default) for
% initializing the solution (TEMPERATURE_FS, DENSITY_FS)
FREESTREAM_OPTION= TEMPERATURE_FS
% Free-stream pressure (101325.0 N/m^2, 2116.216 psf by default)
FREESTREAM_PRESSURE= 11e5
% Free-stream temperature (288.15 K, 518.67 R by default)
FREESTREAM_TEMPERATURE= 303.0
% -------------------- BOUNDARY CONDITION DEFINITION --------------------------%
MARKER_EULER= (Nozzle)
MARKER_SYM = (Symmetry)
MARKER_INLET= ( Inlet, 303.0, 11e5, 1.0, 0.0, 0.0 )
MARKER_OUTLET= (Outlet, 1e5)
`
So what is the possible issues ?
