Hello everyone,

I am trying to run a LES study of a buoyancy driven flow. Previously I ran a few RANS simulations of the same case, and I observed that most of the fields showed a chequered pattern unless I activated IPHYDR and IPUCOU.
In a first exploratory LES, I am back to the same situation ...

Hello,

The boundary temperature I plotted is that output by the calculation, with the postprocessing activated in the GUI in Surface solution control. I attached the temperature field on a mid plane. As you see it is rather irregular, and also the time evolution at my monitoring points is unstable ...

Hello Yvan,

The calculation itself is very unstable, but I thought that it could be either independent or even caused by the boundary problem. But that is because I assumed that imposing a Dirichlet boundary condition would force the boundary temperature to the chosen value no matter what happens ...

Hello everyone,

I need to impose a "no-shear wall" boundary condition with uniform temperature in a test simulation. I have found a ready-made recipe for it in the user manual (for version 4, in the notes at page 74), which I implemented as follows in cs_user_boundary_conditions:
if (constant ...

Hello,

Sorry for the late reply, I attached config.status and the Makefile in my build directory (hope is the one you meant). I had a glance at them and the variables concerning hdf5 seem reasonable. Hopefully you can get more from them.
Thank you again and regards,

Cosimo

Hi,

It worked when I added /opt/Salome/BINARIES-UB16.04/hdf5/lib, which I had already tried but I did not think of restarting the GUI.
Thanks for that. Can you suggest me the modification to the script?
Regards,

Cosimo

Hi Yvan,

Many thanks for your answer. I am running Ubuntu 16.04.1, 64 bit.
The configure.log I posted is just what the configure command printed on the standard output, I did not use the installer. I am attaching config.log in the hope it is more helpful.
I am using Salome 8.2.0, the pre-compiled ...

Hello everyone,

I am trying to install the triplet Salome + Saturne + Syrthes on a new workstation, but I encounter a problem I never had in my previous installation.
I make use of Salome's libraries, and nothing seems to go wrong during the compilation: in particular, at the end of the configure ...

Hello Yvan,

I think I have located the cause of the problem: in usipsu I called field_set_key_int but I had not initialized ifcvs. It is an old bug but it went unnoticed because it did not cause problems with my production installation. Perhaps uninitialized variables are set to 0 by my compiler ...

Hello,

I am experiencing a rather peculiar problem using version 4.0.1: when I run my simulation using my debug install, I get an error I do not have when I use my production version.
The error occurs in iniva0: I tracked it down to the line:
call field_get_key_int (ivarfl(isca(iscal)), kivisl ...
