code_saturne User's Forum

Hi all,
as you said before, the strong jumps that i impose have a very strong influence on simulation convergence and stability. Is there any theoric advice you can give me to increase code stability ? i'm already using upwind schemes with SIMPLEC.

Thanks

Hi all, i want to set a particular kind of head loss definition. Using cs_user_head_losses.f90 i'm trying to set for each cell a particular condition: 1- start: all cells are initialised to 0 (this is set by default) 2- after 100 iterations there is one head_loss penalisation iteration: scanning all...

As to how you drive the optimization process itself, I assume you need to drive a succession of computations. The built-in autovnv framework might be sufficient for this. Otherwise, SALOME has some features for parametric studies, or you can roll your own scripts, depending on what fits best. Hi Yv...

Hi jtache,
for what is my experience i worked on porosity values importing their value also in cs_user_extra_operations, such subroutine is loaded at the end of each time step, and thus i'm able to have a changing porosity value

Hi, following your advice i'm trying an optimization following the SIMP algorithm (esponential behaviour from max to min viscosity) instead of a BESO algorithm (0-1 viscosity). I'm running some slow single core simulations just to test the algorithm. However i want to scale to fully parallel. As you...

Hi Yvan, after some studying about the principles of topological optimization, now i'm a little bit more conscious of what I should do. My goal is to maximize the heat transfer at the wall in a water cooling circuit defining the best flux shape. According to theory, in first instance, i should incre...

Hi all, as stated in the topic i'm interested in find a way to use code_saturne as a cfd topological optimizer. If you search something on youtube there are some solutions made by commercial software. It could be interesting for applications such designing pipes and collectors. Similar on what is po...

really thank you ! directly linking the libraries is working. I'm wondering why it can't find, for example, BLAS by himself but it's ok with --with-blas=/usr/lib/libblas Is there any way to check if the software is able to browse usr/lib folder in search of pre-requisites? if not i'll manually provi...

Yes, i checked from synaptic and i have installed: Hierarchical Data Format 5 (HDF5) - development files - serial version Hierarchical Data Format 5 (HDF5) - development files - OpenMPI version Hierarchical Data Format 5 (HDF5) - development files - default MPI version Development files for libmed D...

Hello Yvan, thank you for the fast reply and sorry for not attaching config.log
I run configure in another separate directory but the error is still there. this time I have attached the log file.

Thanks in advance.
