Summary

Value from a polynomial function

Description

The value, $\phi$ , is calculated as $\phi = \sum_i^n C_i (X + X_0)^i$ where $X_0$ is the variable offset, $X$ is the variable, $n$ is the order and the coefficients provided are $C_i$

The following options are present in most boundary conditions/sources. The meaning of each option is as follows:

Power_Output: If specified, the total (integrated) power of the given BC/Src is calculated and stored into the global variable name specified as the power_output argument.
Flux_Output: If specified, the average flux of the given BC/Src is calculated and stored into the global variable name specified as the flux_output argument.
Toggle: If given, specifies which toggle block controls whether this BC is active or not.
