7.2 tUtorial 10 (a): thermal-stress
analysis-seqUential CoUPled field

In this tutorial, the thermal analysis of an axisymmetric pipe with fins
and sequential-coupled field is introduced. Continue the axisymmetric fin
problem from Tutorial 9 to do a thermal-stress analysis. The pipe has an
internal pressure as shown. Also, as the top line (at Y = 1.0) represents a
line of repetitive symmetry, we will couple the UY degrees of freedom of
all nodes along that line.
