Mesh refinement by the macro command MACR_ADAP_MAIL
[under construction - just started 2010-02-21 ... ]
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 quite simple in order not to disturb the issue we would like to show with other difficulties. We try to refine the mesh of an L shape with a few holes in it. The thickness of the two 'legs' are 0.8 mm and 1.2 mm. The diameters of the holes vary between 0.9 and 1.0 mm. Overall dimensions of the shape are 5 * 6 * 7 mm3.
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] = [5.0, 6.0, 7.0]
- width of the legs: 1.2 mm vertical and 0.8 mm horizontal
- diameters of the circles: in vertical plate: 0.9 mm - in horizontal plate: 0.8 mm
- radii of the fillets: innerfillet 0.5 mm - outerfillet 1.2 mm
The mesh consists of coarse, tetrehedral elements to start with.
The load of the construction
The L shape is fixed in all directions at the bottom area Afix. On area at opposite end of L is denoted Apres. For simplicity, on this area a displacement of 0.1 mm is given in the y direction.
