FEMVIEW Command only.
This command displays a surface representation of the current finite element model. The command is only effective with models comprising 3-dimensional solid elements.
| Side | View_angle | Comments |
| EXTERNAL | -- | All free element faces are displayed. |
| TOP | See below | See below |
| BOTTOM | ||
| FRONT | ||
| BACK | ||
| LEFT | ||
| RIGHT |
The key-words `TOP', `BOTTOM', `FRONT', `BACK', `LEFT' and `RIGHT' define view points at infinity at the corresponding side of the display screen. (e.g. `RIGHT' means a view point at infinity to the right of the screen). A surface normal is calculated to each element free face that is oriented to the observer and the element face is displayed if the angle between its normal and line of sight from the view point is less than or equal to the specified `view angle'.
The `VIEW FACES' command also provides valuable connectivity information as it draws faces oriented towards the observer which it identifies as 'free' i.e. not connected to other faces. Thus a spurious face drawn within the body of the model may identify connectivity problems.
Examples:
Draws free faces pointing to the the left, such that the normal to each surface will be 30.5 degrees or less to the line of sight.
Draws all free faces.
