Feature tested

User subroutine to provide internal heat generation in heat transfer analyses.

Problem description

A two-dimensional rectangular block of material, 10 × 2, has heat generated within its volume by user subroutine HETVAL. The value of the generated heat flux is r = 0.40483. The material has specific heat, c = 0.1431, and density, = 0.2829. A transient thermal analysis with all edges of the volume insulated should give a temperature rate of

Results and discussion

Time is incremented by 5 units in each increment of the analysis. From the equation above, therefore, nodal temperatures should increment by 50 units during each increment.
