Summary

User vector field influx energy flux

Description

Flux is given by:

(M)(SC)(GV)fcn(t) \vector{f} \cdot \vector{n}

M is given by MULTIPLIER, SC by SCALING, GV by the value of the global variable with name GLOBAL_VAR, fcn is a function with name TIME_FUNCTION, f is a field with name NAME, and n is the surface normal. Flux will be capped at zero (inflow only)

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.
