«Initial Value [V]»
The initial voltage is valid for all capacitor types. Enter a numerical value, a variable, or an
expression in the text box to define the initial voltage or use the pin to connect a quantity.
The value is set only once at simulation start.
� � «Use pin»
If the box is checked, the initial voltage is defined by the quantity connected to the pin, otherwise
the value in the text box is used.

The capacitance is equivalent to the present value of the quantity specified in the text box.
For the quantity any numerical value, variable, mathematical or logical expression can be
used. Usually a Constant value, a Time function or a variable are chosen, or the value of the
resistance is determined in a state graph. A mathematical expression must conform to the
syntax of the SIMPLORER expression interpreter. All system quantities and variables can be
combined with mathematical and logical operators and constants.
However, the expression must be technically meaningful. If it is not, numerical instability or
completely wrong results are possible. In particular, sudden changes in the first derivation of
the control quantity should be avoided.
