  - Convection Coefficients
    A reference for some typical convection coefficients.
Post Processing
Run analyses and view a variety of results in SimSolid Cloud.
Design Study
Design studies allow you to quickly evaluate and compare the structural performance from different design scenarios.

Convection

Specify the convection coefficient and ambient temperature on a given set of faces.

The Ambient temperature defines the temperature of the bulk fluid, which is assumed to remain constant during the analysis. The convection coefficient defines the rate of heat transfer between the bulk fluid (liquid or gas, buoyant or moving) and a surface of your model. The convective coefficient is equal to the heat rate per unit area per unit temperature difference between the model surface and the bulk fluid. Units for convection coefficients are: W/(m²⋅K).

On the Project Tree, open the Analysis Workbench.
Next to the Thermal analysis branch, click (Expand).
Next to Thermal conditions, click > Convection.
In the modeling window, select one or more faces.
The faces are listed in the Thermal convection dialog.
Optional: Select the Add tangent faces check box.
For Ambient temperature, specify a value and unit.
For Convective heat transfer coefficient, specify a value and unit.
Click OK.

Tip: Occasionally, it may be necessary to pick many convection faces. If this results in too many load icons on the model, select Simple load & constraints from (Settings) > Appearance.
