Hey meysam

Sorry for my late replay. I have overseen the email notification that you wrote to this thread. To your question ... Actually, I made it already public. You will find it under the following link.

github.com/FIPE-System/code_aster-paralell_installlation

Just add the normal https:// at the beginning of the link ;-) (forum restrictions)
Have fun and good luck

#2 Code_Aster usage » Code_Aster Stops without any Error at REPE_OUT » 2022-03-11 07:56:10

Hey Guys,

I have a parallel code_aster installation with mumps and pestc and when the simulation finish until the last step it works perfectly fine. Mostly however, the simulation will stop in between and needs some adjustment. The problem is, when the simulation don't reach its end then the solver just stop at the command RAPE_OUT and as code_aster gives no response I don't get a hint to solve this problem.

Has someone of you an idea how to solve this problem ?

If more information is needed, just ask. The .mess .comm  .export and a screenshot of the terminal are attached.

Thanks for your help

Regards Daniel

Hello Guys

The last couple of weeks i spent some time to install code_aster on my computer (24 Core 128 GB RAM) an was able to do the following:

code_aster version 14.6

1 Step: Simple installation Code_Aster with GNU compiler

2 Step: Parallel mpi (PETSC & MUMPS) installation code_aster with GNU compiler

3 Step: Simple installation code_aster with intel compiler and intal lablas (math library)

Then on the fourth step, I don't find any information on how to compile all the libraries with intel like:

ScaLAPACK (should be also used from the intel library)
SCOTH
parmetis
mumps
petsc
and finally of course aster itself

I used the Intel® oneAPI HPC Toolkit of Intel:
"xxx.intel.com/content/www/us/en/developer/tools/oneapi/toolkits.html#base-kit"
"xxx.intel.com/content/www/us/en/developer/tools/oneapi/toolkits.html#hpc-kit"


Is there any documentation, tutorial or something which could help me with this task? I was not able to do it by my self.

Can you build parallel version with help of snap.

saw your gitlab,, if you can mention all steps of installation, even codeaster, how to download in snap...for non-experts in computer it will be much helpful.


Hey. Actually i don't know as this would be my first build of a snap. But I guess yes, as the base system is a ubunut 18 LTS. The installation process of a deployed/published snap is quite easy. You just have to install snap (the bas system) like:

Fedora:
sudo dnf install snapd
sudo ln -s /var/lib/snapd/snap /snap

Ubuntu:
It is mostly already installed. As it originally comes from the ubuntu system.

Then there are a lot of programs available to install for the user. Like FreeCAD or LibreOffice and others.
If the creator of the new snap (for example aster) published it in the snapstore, any user can install it with:

sudo snap install aster (if aster is the package name)

Done! Different Versions like code_aster 13 and 14 are possible even beta and soon.

I hope i was able to answer your questions ? As i said my knowledge of the code_aster installation process is not enough to create the snap by my self :-(

regards

Hello Guys

I really love to use code_aster, but mostly in a programming/automation way. For this i have to always install code_aster by itself not in Salome Mecca. As you probably know, this can be really painful. So i thought to solve this problem for all (or at least most) linux and mac user (as for windows there is a good alternative) i would crate a snap version.

Snap (snapcraft.io/) makes it really easy to install software, as it runs in a sandbox and the dependencies are shipped with it. The creation of a snap should be also not so hard as you can see in this documentation snapcraft.io/docs/creating-a-snap. But still i struggle with the installation of code_aster, as the always refer to the wrong libraries. There is a lifecycle: pull -> build -> stage -> prime -> snap (snapcraft.io/docs/parts-lifecycle) and everything in the prime folder in the end will be snapped. But after the installation of code_aster it refers to libraries outside the prime folder (mostly /usr/lib ... and so on).

I created a repository (gitlab.com/code_aster/code_aster_snap) with the stuff i did already to create the snap. Is there someone of the creators/maintainers of code_aster (or anyone else) how could help me? It would be really helpful as the installation of code_aster could be always be easy and perfect with all its dependencies!


Regards Daniel

PS: As a sidenote, the performance of a snap should be close to the same (or at least not much slower) as a clean installation.

#6 Code_Aster usage » Liasion_DLL: bind two Point cylindrical » 2017-06-08 15:42:34

Hello guys

I'm Daniel and i need help for my bachelor thesis. I working on a Simulation of a kind of a spring with Beam elements. I have attached my Comm-File and a picture of the Modell.

Some imputs to the Modell:
- Lagre Displacement (GROT_GDEP)
- MULTIFIBRE Beam-Modell (POU_D_TGM)
- non-linear-Material

The problem is, that there is no implementation of a cylindrical coordinate in code_aster and i have to bind the in the picture green marked points in a cylindrical way. If i do it in a Cartesian way, like i do it know with Liasion_DLL, the results are wrong.

-> I tried it also with LIAISON_CYCL, but i got always a error, probably i misunderstood the documentation .
-> I tried it also to change the factor of the LIASION_DLL, but thy should changing with every iteration and i have no idea how to calculate those factors every iteration.

Is there any possibility to bind those two nodes in a cylindrical way ?

If you need more information please ask.

Thanks for Your help
Best regards
Daniel Steinegger

Hey every one

I'm looking for a modalisation of a slender structure with for example a Beam or Pipe elements.
It should incorporate:
