Hello,

i am working on a project where i want to access the nodal temperature of an axisymmetric element (CAX4RHT) in a coupled temperature displacement analysis at every increment with a user subroutine.

The nodal temperatures represent the surface temperature of a solid material (corresponding nodes are combined in a set). The nodal temperatures should be passed to an existing user element (user subroutine UEL) for every node at every increment, where a heat flux should be calculated.

I am not sure where and how i should extract the Nodal temperatures. I am kind of confused with the definition of coordinates and the degree of freedom. Is NT11 a coordiante or a degree of freedom, and how do i access this values?

Thanks in advance.

Feel free to ask for more detail, if you think it would help you to answere my question.

Greetings Lukas
