F. Solution Options

As with all analysis types in Mechanical the “Analysis Settings” can be used to set solution options.

•Note, the same Analysis Data Management options discussed in chapter 4 regarding static analyses are available in thermal analysis.

… Solution Options

To perform a thermal-stress solution link a structural analysis to the thermal model at the Solution level.

An “imported load” branch is inserted in the Static Structural branch along with any applied structural loads and supports

G. Results and Postprocessing

Various results are available for postprocessing:

•Temperature

•Heat Flux

•“Reaction” Heat Flow Rate

•User defined results

In Mechanical, results can be requested before or after solving.

• A new solution is not required when retrieving new results from a solved model.

… Temperature

Temperature:

•Temperature is a scalar quantity and has no direction associated with it.

… Heat Flux

Heat flux contour or vector plots are available:

•“Total Heat Flux” and “Directional Heat Flux” can be requested

–The magnitude & direction can be plotted as vectors by activating vector mode

… Reaction Heat Flow Rate

Reaction heat flow rates are available for Temperature, convection or radiation boundary conditions:

•Reaction heat flow rate is requested by inserting a reaction probe.

•A short cut is to drag and drop a boundary condition onto the Solution branch.

H. Workshop 10.1

•Workshop 10.1 – Steady State Thermal Analysis

•Goal:

–Analyze the pump housing shown below for its heat transfer characteristics.
