*FLUID BULK MODULUS

Define compressibility for a hydraulic fluid.

This option is used to define compressibility for the hydraulic fluid model. It can be used only in conjunction with the FLUID BEHAVIOR option.

Optional parameters

DEPENDENCIES

Set this parameter equal to the number of field variable dependencies included in the definition of the fluid bulk modulus, in addition to temperature. If this parameter is omitted, it is assumed that the fluid bulk modulus depends only on temperature. See Material Data Definition for more information.

Data lines to define compressibility for a hydraulic fluid

First line

  1. Fluid bulk modulus, K.

  2. Temperature.

  3. First field variable.

  4. Etc., up to six field variables.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than six)

  1. Seventh field variable.

  2. Etc., up to eight field variables per line.

Repeat this set of data lines as often as necessary to specify K as a function of temperature and field variables.
