Dear All,
I was wondering if someone experienced could reply me. I've already analyzed a model and extracted the nodal stress tensors. Now the aim is identifying the external model nodes and its corresponding stress tensors and then re-apply them as a new Boundary Condition. Firstly, it seems that I need to multiply these stress tensors (which vary node by node) by a normal vector resulting traction vectors. But, here is the question, how should I define these traction vectors on external nodes as Boundary condition? On the other words, if I wanna apply these surface traction vector as concentrated force I need to multiply traction vectors by an area (somehow node area!?) which I don't have any idea about it. Any suggestion is truly appreciated.
