UNITS

Model ElementUNITS defines the units for the model being defined.

Description

UNITS allows you to specify four types of units

  • Mass
  • Length
  • Time
  • Force

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"
/>

A string that defines the mass unit. Choose from:

  • Gram
  • Milligram
  • Kilogram
  • Megagram

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"/>
