By default, this feature defines a temperature boundary condition. By using the option '''Concentrated heat flux''', one can specify a heat flux value (in mW) in each node belonging to the selected geometrical entity.

Description

Defines a temperature boundary condition or, optionally, a concentrated heat flux load.

Usage

  1. There are several ways to invoke the command:
    • Press the Temperature boundary condition button.
    • Select the Model → Thermal boundary conditions and loads → Temperature boundary condition option from the menu.
  2. In the 3D view select the objects the boundary condition should be applied to, which can be a vertices (corners), edges, or faces.
  3. Enter a temperature to apply to the objects.

Option

By default, this feature defines a temperature boundary condition. By using the option Concentrated heat flux, one can specify a heat flux value (in mW) in each node belonging to the selected geometrical entity.
