dear All,

I hope anyone can help me out. I'm wondering is it possible to create a surface with the help of nodes? the node labels are available in my model, but, I have to pass a surface through every4 nodes to create surfaces. I need these surfaces to apply surface tractions.

Thanks

Thank you for the reply. Actually, I've already analyzed a model and extracted the stress tensors from nodes. Now the aim is identifying the external model nodes and its corresponding stress tensors(which they're already obtained) 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? Does it make any sense at all? 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.

Attached there's picture of my mesh model.

Many thanks for your time.
