Dequations Panel
Use the Dequations panel to create user-defined functions for responses and design properties.
Guidelines for Entering Equations
- Each dequation definition may consist of one or more equations, which are separated by semicolons ( ; ). A semicolon must not follow the last equation.
- The first equation must take the following form:
f(x1,x2,...xn) = (some mathematical expression referencing all of the variables x1,x2,...xn )
- Subsequent equations may reference the resultant variables of the previous
equations in the following manner:
f1(x1,x2,...xn) = (some mathematical expression referencing all of the variables x1,x2,...xn )
f2 = (some mathematical expression referencing f1 )
f3 = ...
...
fn = (some mathematical expression referencing f1,f2,f3,...fn−1 );
- Constants may be specified as integers or in a floating-point format. A floating-point number can be in a format of either normal decimal-point format (3.90) or scientific notation (2.0E-3.0).
- Only alphanumeric characters may be used in variable names. ( You may not use underscores, monetary symbols, punctuation symbols, or mathematical operators in variable names.)
