#1 Re: Salome-Meca installation » Salome_Meca V2019.0.3_Ubuntu 18.04 Installation Issues » 2020-08-24 11:24:10

The following worked on our machines - and (cross my fingers) this seems like a very stable SMECA.  Doing a simple case I was able to generate a simple geometry, add groups, mesh it, add the mesh groups, move into ASTER Study, use the Assistant, run the case, then PostProcess and then I went back to Geom, Smesh, Shaper - then back to AsterStudy, then back to PostProcess - all without crashing (I have never been able to do this before without a crash).

You're going to get SSH access to a Linux VM and have to do everything on your own from there. You should use Virtualbox, Hyper-v or similar to set up a Linux VM on your local PC (with no graphical environment) and then try to configure Docker and what ever else you need to host the site inside your local VM. If you can do that then go ahead with Digital Ocean or Vultr.

#3 Re: Code_Aster usage » Error when using force_face » 2020-08-24 11:20:49

the error says, that you tried to address a group in your FORCE_FACE command that is not present in your model. Maybe you forgot a group? If you created your groups in the geometry module, did you import them to your mesh also ('create groups from geometry'-command in Salome)? Did you enter the group names in Aster by hand (typo)?

#4 Code_Aster usage » Rigid body + towing cable » 2019-03-28 08:25:06

Hello everyone,,
I try to design a simulator of the dynamic behavior of an underwater body towed by a cable.
One end of the cable is considered fixed. The other is linked to the body and there is a current creating hydrodynamic efforts.
At this time, I am able to solve the cable alone in Code_Aster, considering that the mechanical action of the body is just an effort. The next step is to add the dynamics of the rigid body. I know the mass characteristics of the body and the hydrodynamic forces (which depend on movement) on the latter. The last unknown is the effort of the cable. Thus, I have to solve the fundamental dynamic principle of the body in Code_Aster, during the resolution of the behavior of the cable.
How could I do that? I thought of a Python function, but for the coupling problem, I should solve the cable (with DYNA_NON_LINE) and the body in the same time ..
Any idea ????
