regarding boundary condition for solid body

[ankitkumar26jan]

hi everyone,

I am working on a thermal analysis on solid body 3d part. I cut into the small part as shown in the figure. what will be the boundary conditions in Abaqus?
The figure in 2d but I am working on 3d, where I applying flux on one small area.

When you don't know what's going on on that surface, then you can't divide the body there and replace it with a boundary condition.

can we solve semi-infinite heat transfer problem in Abaqus?
