- STFunc
STFunc Block¶
Many blocks in Vorpal can use space-time functions. These are normally contained within other classes that require time signals or spatial profiles, such as Initial and Boundary Conditions.
When using an STFunc block, place the function in its own STFunc
block, specifying the function using the kind
parameter
as in the Example STFunc Block Usage.
Users can make use of kind = expression
to write their
own functions.
Descriptions of STFunc parameters are described on each STFunc kind page.
STFunc Kinds¶
Example STFunc Block Usage¶
<FieldUpdater currentSource_0>
kind = setToSTFuncUpdater
lowerBounds = [0 0 0]
upperBounds = [10 20 30]
component = 1 # J_x, rho is component 0
writeFields = [SumRhoJ]
<STFunc sourceFunc>
kind = expression
expression = 3.*exp(0.1*(t-10.)^2)*sin(3.14*t - 7.2*x)
</STFunc>
</FieldUpdater>
