Code_Aster Evaluation Engineer: Francisco Quesada Trainee: Valentino Revelo Code_Aster Evaluation
INDEX Context Objectives Code_Aster overview Validation Code_Aster deployment Conclusions
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
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
3.- Code_Aster overview Code_Aster Introduction Code_Aster Documentation Code_Aster Download Code_Aster Forums Code_Aster and Quality needs Salome CAE-Linux / CAE-Linux Forums Windows distribution Code_Aster Partners
4.- Validation Windows distribution Emulated native Linux distribution
Code_Aster Windows distribution One-dimensional cantilever beam analysis. REQUIREMENTS: Solve for maximum deflection Reaction at point A Maximum Stress
Code_Aster results Displacements Stresses
Theoretical vs. Code_aster results THEORETICAL RESULTS Code_Aster ANALYSIS % ERROR Maximum Deflection -1.32 0.02 % Reaction at point A -10,000 0 % Maximum Stress 5.56E+08 0.08 % * Note: mesh dependant results

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
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
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)
