What is the meaning of unit real constant in ANSYS?

The unit real constant Real is a supplemental definition of the selected unit, for example, if you do beam analysis, Real can define its beam area and moment of inertia, etc.; if you choose the spring unit, then Real can define its stiffness and damping and other parameters.

It's not that every cell has to define Real constants, it depends on the need.

Generally the default can be calculated, the specific settings are very troublesome, according to the actual problem, and the actual contact with the more varied, can only look at the problem.

Set the Real Constants and Element KEYOPTS. This can also be seen, simply set the real constants does not make sense, need to be used in conjunction with the key terms, it is recommended to use a variety of parameters by default.

Extended information:

Properties of a cell include geometric properties (position, size, etc.), physical properties (modulus, dimensions, etc.), and physical properties (moduli, etc.). ), and physical properties (elastic modulus, Poisson's ratio, etc.). Real constants have different uses for different units, the general uses are:

1, beam unit: beam unit modeling is just a line, in order to set the unit's area, moment of inertia, height, and other attributes, you need to set the real constants.

2, plate and shell unit: plate unit modeling is just a surface, the thickness of the surface and other attributes to be able to set the real constant.

3, solid unit: for planar quadrilateral unit, if the plane stress problem and the thickness is not 1, to set the thickness of the unit in the real constant.

4, spring unit: spring unit modeling is just a line, spring stiffness, damping coefficient, etc. to be set by the real constants.
