Discrete load on a cube surface
Posted: 16 Feb 2011, 11:08
I've managed to run (mostly using ElmerGUI) a simulation of a fully supported (sides and bottom) cube with a point load vertically downward onto a small area at the centre of the top surface.
I first manually wrote a .grd file to define a cube with 10x10x10 elements and one boundary per side (six boundaries), and then used ElmerGUI to find the element numbers of four elements at the centre of the top surface. I changed the elements' boundary numbers to seven by manually editing the boundary mesh file, reloaded ElmerGUI and applied the force to that boundary. I used ElmerPost to visualise the displacement into the cube.
I was wondering if it would be possible to automatically generate my cube (with the seven boundaries) using just the .grd file? This way I wouldn't have to do any manual edits to the generated mesh files. I have read the ElmerGrid tutorial extensively and I am very lost
I have attached some images of the model to help explain the situation.
Thanks!
