Element Convection Boundary

In the heat of hydration analysis, the restrictions applied to the stress analysis model are convection limit, adiabatic limit, and prescribed temperature limit. Convection limit (or heat transfer limit) is the limit at which heat is transferred between ambient and temperature analysis model. Define conditions of the convection limit by assigning the convection coefficient and the ambient temperature.

From the Main Menu select Load > Heat of Hydration > Hydration Heat Analysis Data > Element Convection Boundary.

Boundary Group name

Select the Boundary Group Name, which contains the entered boundary condition. Select "Default" if a Group definition is unnecessary. Click the button to the right to prompt the Define Boundary Group dialog box to add or modify groups.

Option

Add/Replace
Enter a new or modify a convection boundary condition.

Delete
Delete previously defined convection boundary conditions.

Convection Boundary

Specify a convection coefficient function and an ambient temperature function.

Convection Coefficient Function: Select a predefined convection coefficient function.

Ambient Temperature Function: Select a predefined ambient temperature function

Selection

The convection boundary condition is specified with respect to the surface of solid elements. Specify the face of the selected solid elements by the following:

Face#: Select the (surface) face number and specify the elements to select the element surface. The (surface) face # of the selected solid elements is determined by the order in which the elements are generated. The selection is highlighted on the model, which allows us to ensure that the current selection is correct.

By Selected Nodes: Select the face of the solid elements, which is defined by user-defined nodes.
