Model Element

Description

UNITS defines the units for the model being defined. UNITS allows you to specify four types of units

The last is obviously a function of the first three and can be automatically calculated for a consistent set of units. However, many unit systems are not "consistent", so it may be necessary to specify a force unit also.

Format

<UNITS

     force       =   "string"

     mass        =   "string"

     length      =   "string"

     time        =   "string"

/>

Example

The following is an example of an NLFE component defined in using Newton, KG, MM, S units:

<UNIT force="NEWTON" mass="KILOGRAM" length="MILLIMETER" time="SECOND"/>
