ForceDensity¶
Type: | 1-Tensor, or section |
---|---|
Range: | [v_1, …, v_3] |
Default: | -/- |
Appearance: | optional |
Specifies a mechanical force density, , as used for continuum mechanical problems. Units are newtons per cubic meter, .
Note
A ForceDensity
is only definable for a physical domain. So, setting BoundaryId
in the parent section is not allowed.
A constant force density can be defined by assigning a 3-vector:
# define a constant force density
ForceDensity = [..., ... , ...]
For more general cases, a force density may be given as a section in order to deal with space, time, and parameter dependent definitions:
# define a force density as a section
ForceDensity {
Constant {...}
Python {...}
...
}
Field definitions within this section are summed up. Consult the subsequent sections to see which types of field definitions are allowed.
