Second order scheme with RANS

[Roxan]

Hello,

I would like to know if it possible to use a second order time scheme for momentum equation with RANS turbulence models (k - omega SST exactly).

I try to put ischtp = 2 in cs_user_parameters.f90 but I had an error :

@ @@ WARNING : STOP AT THE INITIAL DATA
@ =========
@ A 2nd ORDER SCHEME HAS BEEN IMPOSED (ISCHTP = 2
@ FOR K-OMEGA (ITURB = 60 )
@
@ The current version does not support the 2nd order with
@ coupling of the source terms of k-omega.

I understand that second order schemes are not available for k and omega equation but I would like to know if it is possible for momentum equation like it is the case for LES models.

I am using Saturne 7.0.2 version

Best regards,
Roxan
