A list of the boundary conditions used in ABAQUS. U1, U2 and U3 specify movements along Table 1. UR2 and UR3 specify rotation about the x, y and z axes, respectively. The fundamental units in the SI system are length in meters (m), mass in kilograms (kg), time in seconds (s), temperature in degrees kelvin (K), and electric current in amperes (A). The units of secondary or derived quantities are based on these fundamental units. An example of a derived unit is the unit of force. What is the unit of U3 in Abaqus in the result. degree or radian? I performed quasi-static analysis on gears in ABAQUS. After analysis, I extracted the U3 parameter to measure the gear eYCcy7l.
