BCs (Boundary Conditions):

Temperature

Heat Flux

Heated Volume

Convection

Radiation

Point Source

Velocity

Resistance

Voltage

Current

Variation

Once the geometry has been created, the appropriate boundary conditions should be associated to the geometry (typically surfaces or blocks). Each boundary condition form is of a similar format, with a "Plane" section where you choose the location and the "Data" section where you specify the respective value of the condition (which can be constant or varying based on temperature, time, etc.). Some boundary conditions can be associated to different types of geometry and some have extra values to be specified.

Create / Modify: Make sure you have selected the correct radio button depending on whether you want to create a new boundary condition or modify an existing boundary condition. Name: Duplicate names are not allowed for boundary conditions and the names cannot include spaces or the following characters: ( ( ) [ ] . , ). Names are not case sensitive.
Modify: All of the existing boundary conditions of the respective type will be displayed in the listbox below the Modify radio button. First select the BC and then the current values will be displayed. The panels will be disabled when nothing is selected to ensure that you don't try to modify nothing. Hide / Hide All: Hide will immediately hide/show the BC. Hide All will do this for all BCs of this type.
Plane - Associated to Geometry: Specify the geometry (Surfaces, Blocks, Solids, Nodes) that this boundary condition defines. Selection Controls can be used for easier selection of geometry, allowing you to click on the appropriate geometry that will automatically be placed in the text box. Selection Controls, Geometry Hierarchy
Plane - Specified Region: Specify the area that defines the boundary condition. Most boundary conditions are planar, so you will be required to enter the normal direction and then the 5 necessary XYZ values. Use Point selection controls for quicker location entry. Note that Specified Region should only be used in cases where the boundary condition cannot be associated to a selection of geometry. This is because spatial (specified region) boundary conditions will not move with the geometry if it is later moved. Associations to are also much clearer with geometry and one boundary condition can specify a group of regions rather than just one region.
Data - Constant: Enter a value that will stay constant throughout the entire solving process.
Data - Variable: Select table(s) and/or function(s) to define the value of the respective boundary condition. You may select from already created tables and functions or click to create a new table or function and then add it to the "Active Table / Functions" list. You can also use the details button to view the table/function selected in the combobox. Tables, Functions
Copy / Move: Copy and Move are available for boundary conditions that are not associated to geometry. You can copy the BC any number of times and each copy will be moved by a multiple of the dX,dY,dZ values. For example, if 4 copies are to be moved with dX = 2, the third copy will be 6 units away from the original copy.
Include in Analysis: This tells whether this boundary condition will be used when running the solver. Apply: After clicking apply, the BC will be created and a message will be shown in the command window giving the session call and comment.
