Dear code_saturne team,

I am using the Mapped Inlet in GUI to define the inlet condition for my LES calculation of a regular pipe.
I only want the velocity field to be fed back but It seems that the temperature field is also mapped.
So I modified the cs_user_boundary_conditions-mapped_inlet.f90., but it didn't work out.

I just want to map the velocity iw, without changing the temperature of the inlet.
Could you help me find out my problem? I guess there might be something wrong with my normalization process, or else.

Any suggestion will be appreciated. Thank you in advance.
Bonne journée,
Gen

Hello,

You are looping on all fields and applying the mapping to all of them (even for non-solved fields, to which this does not apply),, so that is why the temperature is mapped also.

You need to call boundary_conditions_mapped_set only for the velocity field if you only want the mapped inlet for velocity.

Yvan
