Linear elasticity of Sphere

Post by TheWonder34 »

Hello, it's my first post here, so sorry if it's in wrong place.
My problem is as follows: I need to apply a force to a sphere (to see in ParaView how deformation looks), but I can apply force (as Boundary condition) on the entire surface. And my question is (one of three, but if anyone knows, then can answer to all of them): how I can aplly force to only one surface (one of the polygons on that sphere) or/and how can I press one object to another in Elmer (one object has a force to press on that sphere) or/and how can I wrote *.grd file, in which I can make another boundary (like in this topic: viewtopic.php?t=1157&fbclid=IwAR1_jB89_ ... wrgr_dJR8w ). Thanks for replies!

For contact between bodies see the elmersolver manual page 46
http://www.nic.funet.fi/pub/sci/physics ... Manual.pdf
and the test problems beginning with Contact at
https://github.com/ElmerCSC/elmerfem/tr ... /fem/tests

Appendix A of the elmersolver manual has the mesh file formats you would edit the mesh.boundary file
if you know the boundary element number the second column is the boundary number it belongs to.
