Code_Aster deployment
Conclusions

3. 1.- Context
Internship between University of San Carlos and Técnicas Reunidas
In this context Valentino Revelo has worked for Tecnical (Heat Transfer Division) at Heaters Mechanical Design Department
This project was conceived in order to afford the FEA software license needs

4. 2.- Objectives
Install and run Code_Aster for its different distributions
Validate Code_Aster calculations
Evaluate Code_Aster distributions and its deployment
Test its learning curve with a practical training session

5. 3.- Code_Aster overview Code_Aster Introduction
Code_Aster Documentation
Code_Aster Download

13. 5.- Code_Aster deployment
Main aspects to define for its deployment:
Department size and legacy
Training
Support and maintenance
Commercial packages with more developed geometry modeling (Catia, SolidWorks/CosmosWorks, etc…)
Linux deployment possibilities
Hardware possibilities

14. Code_Aster deployment difficulties
Documentation in French, only basics in English
Linux emulation dependence if its installation is not allowed
Great RAM needs
Linux installation and use difficulties
Different FEA software design and philosophy
No training in Spain

15. 6.- Conclusion
Code_Aster could be a good solution for our needs because:
Reliable FEA software for mechanics, thermals, fluids… according to our multiple domains
Afford FEA license needs with no costs (GPL license)
Free complete online documentation and validation files
Free support from forums
EDF software standard and powered by the French Government to be a FEA standard in the industry
Due to its open source code written in Python and Fortran it allows:
Automated modeling (as in PCL for Patran)
Software customization
Portable calculation environments (emulated version)
