Calculate global stiffness matrix
Hi there folks,
does anyone around here knows about calculation of the stiffness and mass matrices?
I have a regular 3d grid. Some points are moved onto the object and the cuboids are marked whether they are inside or outside.
The inside cuboids form the object and I need to calculate the global mass and stiffness matrix.
Unfortunately I have no idea on how to to this for this 3d problem.
Thanks in advance if anyone is able to help 🙂
