# Constant Damping Block

Constant Damping blocks store the damping coefficient for a given direction.

The following table describes the parameters stored in a Constant Damping block.
Abbreviations are: [A] = angle dimension, [F] = force, [L] = length, [T] =
time.

Parameter | Type | Dimension FX, FY, FZ | Dimension TX, TY, TZ |
---|---|---|---|

C | real | [F][L^{-1}] |
[F][L][A^{-1}] |

If the direction block selects the constant damping formulation for the FX direction,
then the property file, for example, must contain a

`[CONSTANT_DAMPING_FX]`

block. The form of the block
is:```
[CONSTANT_DAMPING_FX]
C = 600.0
```

The dimension for the damping coefficient for translational directions is
[F][T][L^{-1}] and for rotational directions [F][T][L]. When read from
the property file, the damping coefficient is converted from the units defined in
the property file to the solver model units.
