ParsedVectorFunction
Return a vector component values based on string functions for each component.
The ParsedVectorFunction
is a vectorized version of the ParsedFunction. Both the vector components and the curl of the function may be specified. The inputs for the components of the vector and curl of the function follow the same rules as outlined for the ParsedFunction.
Example input syntax
In this example, a ParsedVectorFunction
is used to define a curl boundary condition. Both x,y component and the z-curl are set for this function.
