Predefined Variables
A new model contains a list of predefined variables by default.
A predefined variable may be deleted or modified and only have an effect if you explicitly refer to that variable.
c0 | The speed of light in free space in m/sec. |
eps0 | The permittivity of free space in F/m. |
mu0 | The permeability of free space in H/m. |
pi | The mathematical constant π (Ludolph’s number). |
zf0 | The characteristic impedance of free space in Ohm. |
