Tormenta de ideas

Aplicaciones de mallado potenciales

Algunas aplicaciones de mallado existentes

• Netgen una muy buena aplicación de mallado, LGPL con algunas bibliotecas de soporte
• Salome un paquete complicado, difícil conseguir el código que necesitamos!?
• PythonOCC biblioteca de Python envolviendo las aplicaciones de mallado Salome y Netgen puede ser el modo más rápido y completo de integrar aplicaciones de mallado

Solvers potenciales

Algunas aplicaciones de cálculo existente

• Calculix
• Code-Aster ssolver muy amplio con una cubierta en Python
• PythonOCC biblioteca en Python que también puede ofrecer una (actualmente) basta interfaz a Code_Aster que podría ser un modo rápido de tener la primera solución funcionando
