Mesh refinement of a beam based on displacement

[under construction - just started 2010-02-23 ... ]

To start with, this contribution mainly focuses on the use of Salome, Code Aster and the macro command MACR_ADAP_MAIL. So I do not focus on the results and the mechanical justifications of the code that has been used. So no guarantee that the results will be correct up to five decimal places, which they are probably not. I do hope though that this information is useful. For me it has been, because I had to think about some commands and look through the documentation and learn from that. In case of mistakes, errors or remarks, please notify me, or better, you are invited to correct or edit them yourself. Enjoy.

The geometry

The geometry and the mesh of the construction

The mesh refinement is based on Homard. As usual the geometry is very simple in order not to disturb the issue we would like to show with other difficulties. Here we focus on how the refinement of a beam will be performed. In this case an axial loading on a beam takes place and the refinement is based on the axial displacement. Then it is very easy to follow the refinement process.

The geometry is defined in a python script (for download see end of this contribution) and can be loaded into Salome Geometry module by File --> Load script (or ctrl T in the object browser window). Right click Refresh or push F5 after loading if necessary.

overall dimension: [x,y,z] = [1.0, 23.0, 2.0] mm

The mesh consists of coarse, tetrehedral elements to start with.
