Units

• What units does ABAQUS use? ABAQUS has no
  inherent set of units.
• How do I set the units in ABAQUS? You cannot.
• It is the Users responsibility to use a
  consistent set of units.
• Choose the units for Length and Force
• If the analysis is time dependent then select the
  unit for Time.
• Example Length m Structural
• Force - N
  Analysis
• Time - Sec
  
• 
  
  Then the units for all the
  other quantities are derived from it.
• Modulus, stress Pascals
• Density - kg/m3
