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.
