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 User’s 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

Example : Cantilever - Plate
