Introduction
Example problem 9 has been designed to illustrate the thermally “stiff” problem. Patran Thermal has Iterative (SOL=0) and Direct (SOL=2) solution options. For “stiff” THERMAL problems iterative solvers tend to converge very slowly while direct solvers work very efficiently. The problem is solved using both iterative and direct solvers and the run times are compared.
