Hi,

For example if a hollow sphere with an inner radius of 2 units and an outer radius of 5 units. To define the temperature boundary condition to the inner surface nodes,

CSYS, 2                          ! Actives the spherical coordinate system.

NSEL, S, LOC, X, 2,,      ! Select the inner surface nodes, at a radial distance of 2 units.

BF, ALL, TEMP, 100,       ! Define the thermal boundary conditions to selected nodes (inner surface)

ALLSEL                           ! All select

Thanks
