Dear all, I studied the step- 44 Tutorial Program and read already a lot about how to apply a Neumann contribution. But I have still two questions: In my case, I like to apply a force (not a force per unit reference area) as a Neumann contribution on the RHS. But for the Integral, Ni * traction* JxW I need the Piola- Kirchhoff traction. My idea would be the following: F= PN dA = T dA <=> F/dA= T I would simply divide the force by the area of the cellsurface. So my first question is: Can I do it like this or is there a simpler way of doing it? And the second question is: How can I access this sort of Information? The area might for example be computed using the norm of a cross product. But I am not sure how to get the two vectors for this operation.
Any help is appreciated.
