About Thermal Analysis
Click Home > Analyses and Studies to define a thermal analysis. A thermal analysis measures the effect of thermal loading on your model.
In Thermal, you can define two types of analyses:
Steady Thermal—Calculates steady-state thermal response to a constraint set and one or more optional heat loads. The constraint set is comprised of one or more prescribed temperatures and/or convection conditions. For example, you could define a steady-state thermal analysis to analyze the cooling fins in a lawn mower engine.
Transient Thermal—Calculates temperatures and heat fluxes in your model at different times in response to one or more optional heat loads and subject to one or more optional prescribed temperatures and/or convection conditions. In a transient thermal analysis, you calculate temperatures and heat fluxes in your model at different times in response to specified heat loads, prescribed temperatures, and or convection conditions. You can use transient thermal analysis to find out:
how long your model takes to cool down or heat up
how your model might respond to a time-dependent heat load or bulk temperature
what thermal stresses develop as a result of temperature changes
You must specify at least one load set or one constraint set.
