Hey Everone, I have recently started studying FEM and I have some basic doubts. Hope I can get some clarity here. 1. Is the stiffness matrix defined for element or node? In a simple truss with 2 linear elements, we calculate the stiffness matrix for K(1,1), K (1,2), K(2,1), K(2,2). In K(e,n): e is the element number and n is the node number. So is the stiffness matrix defined for node or element?
2. How is the order of Stiffness matrix calculated? 3. Does the stiffness matrix only depends on geometry and material? are there any other factors? 4. Why is the load vector not symmetrical? In a simple truss with 2 linear elements, why is F(1,2) not equal to F(2,1)? F(e,n): e is the element number and n is the node number.
