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
