Time scheme descriptor.
Members of the time scheme structure are publicly accessible, to allow for concise syntax, as they are expected to be used in many places.
iccvfg |
indicates whether the dynamic field should be frozen or not:
isno2t |
Specifies the time scheme for the source terms of the momentum equation, apart from convection and diffusion (for instance: head loss, transposed gradient, ...).
istmpf |
Time order of the mass flux scheme The chosen value for istmpf will automatically determine the value given to the variable thetfl.
isto2t |
Specifies the time scheme for the source terms of the turbulence equations i.e. related to ,
,
,
,
,
), apart from convection and diffusion.
thetcp |
-scheme for the extrapolation of the physical property
"specific heat" when the extrapolation has been activated (see time_extrapolated field key int), according to the formula
.
The value of = thetcp is deduced from the value chosen for the specific heat. Generally, only the value 0.5 is used.
thetsn |
-scheme for the source terms
in the Navier-Stokes equations when the source term extrapolation has been activated (see isno2t), following the formula
.
The value = thetsn is deduced from the value chosen for isno2t. Generally only the value 0.5 is used.
thetst |
-scheme for the extrapolation of the nonlinear explicit source terms $S_e$ of the turbulence equations when the source term extrapolation has been activated (see isto2t), following the formula
.
The value of is deduced from the value chosen for isto2t. Generally, only the value 0.5 is used.
thetvi |
-scheme for the extrapolation of the physical property
"total viscosity" when the extrapolation has been activated (see time_extrapolated key word), according to the formula
.
The value of = thetvi is deduced from the value chosen for time_extrapolated key word for the viscosity. Generally, only the value 0.5 is used.
time_order |
Global time order of time stepping
