GUI pour Visualisation prétraitement

thomas

Bonjour,

Etant débutant Aster, la grosse difficulté de prime abord est la visualisation de la mise en donnée du modèle (en particuliers pour des shells et beam).
AsterStudy semble assez dépassé et incomplet, y'a t'il des interfaces plus modernes pour cela ?

J'ai commencé à coder une appli pour visualiser le .comm avec affichage volumique des sections poutre et coque, affichage des normales, des efforts, des BC, des masses ponctuelles et ressorts.... bref tout ce qu'il faut dans un viewer EF.
Les résultats sont très concluants avec les paquets python MEDcoupling et Pyvista, mais le problème est que ce code n'est pas qualifié pour une utilisation professionnelle....

I think some of the developers of FreeCAD has considered integration of code_aster solver.
The thing I miss most is pre-/post processing tools facilitating the use of beams. In the old Postpro module (up to SalomeMeca 2013) could visualize moment and force curves along beam elements. As I recall it could also visualize the orientation local x-axis of the beam elements. Nice if you work with beam elements.
Visualisation of layered results of shell/plate elements could be filtered in the postprocessor so what is shown depends on angle of sight (as seen by the operator) so if you see the INF side of elements the INF value is shown and if you see the SUP side of elements the SUP value is shown. Today - as you probably know - you have to make this separation of results in code-aster in order to visualize in Paravis/Paraview.
A material library is a nice feature for the lazy :-)
For the structure of the preprocessor for setting up the comm file it may seem a bit old-school and complex. One reason for that is the feature richness of code-aster. I think this has been addressed in the past by offering templates to make a basic framework for different type of calculations. A good idea if you analysis matches a template but I never use them.
I have occasionally used Calculix and I find the Prepomax pre- and post processor easy to work with, and could be an inspiration but it also lack the features specific for 1D beam elements - for which Calculix is not really good anyway.
Finally a few thing which may be beyound what you have in mind:
When making thermomechanical calculations it would be nice to have a tool for describing temperature depending Youngs module, yield stress, thermal conductivity and thermal expansion. ElmerFEM has a mathematical macro language for such use.
Good luck with the project :-)
