Code aster tutorial for load varying with time and depth

Here I post two tutorial in code aster/ salome meca as follows:
1. Applying varying load
In this tutorial, simple vertical element is considered in which a vertically varying load is applied by defining a function.

2. Analysis of dam for varying water level
This is a typical analysis of dam where water level is assumed to fluctuate with time. Since two variables changes i.e. time and water depth, we need to make an external file to read the pressure (load). This tutorial will show how to do it.

Some clues:

DEGE : deformations generalized on the elements of beam or hull
ELNO: Node- calculation carried out by extrapolation with the nodes of the quantities at the points of Gauss
ELGA:Gauss point
NOEU:

EF~:Effort

SI~: Stress

Beginning with Code Aster and Salome Meca

Code aster is an opensource (free) FEM analysis software targetted to structural, thermal and aucostic analysis. It is available for windows and linux. This software can be used for non-linear analysis and thus is quite useful for engineering studies epscially for academic research. But the sofware is little difficult to use for begineers. I am sharing some introductory videos to get started with this software. You can visit the forum for discussion on your specific problem.

• Analysis of a simple beam

• Non-linear analysis of simple steel rod

• Modeling hardeing of steel

• Analysis of plate and plotting stress strain diagram
