Hi,

Thank you for your reply.
Yes, unfortunately, I'm asking for the thermal conductivity/diffusivity in C code.
Is there anyone know the variable name for it?

Hi all,

Just a quick question. I would like to get the thermal conductivity (or thermal diffusivity as i'm using the enthalpy equation) to use in cs_user_parameters.c.
I try to find it in the doxygen and userguide but seems couldn't find the variable name for it.

Best,

Hi Luciano,

My mass flow at the inlet is negative because of my streamwise domain is in a -z direction(sorry about this confusion).
And when I activate my gravity, the velocity at the inlet is still imposed as it is a mixed convection case.

Sorry for the bad question. I rephrase my basic question ...

Hello Luciano,

I tried to reduce my gravity to 2m.s-2. And still give me diverge calculations. I try to impose extremely low gravity at the moment. But I wondering if this will be the case when I increase the gravity manually later on.

Also, in the cs_user_physical_properties you have a very ...

Hello Mushin,

Could you solve your problem? If not, could you upload a small problem where the case fails.

Regards,

Luciano

Hi Luciano,

Thank you for asking. No, I still haven't solved my problem. I am right now planning to impose my outlet with convective outlet. But still not sure if what I ...

Hi,

I would like to test using the convective outlet (icodcl=2) for my calculation.
I just have some very basic questions on the implementation.

Firstly, I use itypfb of ifrent instead of isolib. This should be right isn't it?

As in the guide suggest, rcodcl(ifac,ivar,1)is the flux ivar at the ...

Hi Yvan,

My mesh is fully structured, and it was running fine for my forced convection case.
The problem only started when I switched on my gravity.

I also checked the possibility of using convective outlet (icodcl = 2) for my boundary condition. Would it help of my unsteady mixed convection ...

Hi

I am working using LES and having an issue with my upward mixed convection with variable properties case. My calculations keep failing where I have backward flow from the outlet into my calculation domain. I've tried both isolib and ifrent as my outlet but both still giving me this problem. For ...

Hi Yvan,

Thank you again for your reply.
I am right now using nonGUI approach.
I wonder how to specified it within subroutines for this temperature at the boundary if I could.

Hi Yvan,

Thank you for your reply.
Just want to check with you with some basic questions.
If I would like to create an additional writer in the cs_user_postprocess.c, I will need to specify the postprocessed variables in the cs_user_postprocess_var.f90 at the specified ipart which equivalent to ...
