![]() ![]() There are numerous different sets of units that can be used when performing FE simulations. In this case, the fundamental units could be tonnes (1 tonne = 1000 kilograms), millimeters, and seconds. For example, Young’s modulus is frequently specified in terms of MegaPascals (MPa) (or, equivalently, N/mm2), where 1 Pascal = 1 N/m2. Sometimes the standard units are not convenient to work with. The definition of derived units is based on fundamental physical relations:įor example, A unit of force in the SI system is called a Newton (N):Īnother example is the unit of energy called a Joule (J): Choosing a suitable consistent system of units The fundamental units in the SI system are length in meters (m), mass in kilograms (kg), time in seconds (s), the temperature in degrees Kelvin (K), and electric current in Amperes (A).Ĭombinations of base and derived units may be used to express other derived units. The International System of Units (SI) is an example of a self-consistent set of units. Generally, any consistent system of units consists of some fundamental units such as Length (L), Mass (M) or Force (F), and Time (T) as base units and the other units are named derived units, which are formed by powers, products, or quotients of the base units and are potentially unlimited in number. Consistent Units (Abaqus consistent units) Read this useful article in 4 minutes to get enough information about Abaqus units or units in Abaqus. Therefore, the units chosen must be self-consistent, which means that derived units of the chosen system can be expressed in terms of the fundamental units without conversion factors. How can I simulate in Abaqus correctly? Is there any tutorial?Ībaqus has no units built into it except for rotation and angle measures.Reference Table for consistent systems of units.Choosing a suitable consistent system of units. ![]()
