Description of the method to obtain the variables, here some preset values might be stored, like the space time function to use or the required variables.
The variable system to obtain the variable from.
Three-dimensional coordinates at which the variable should be evaluated. Only useful for variables provided as space-time functions.
Point in time at which to evaluate the variable.

Resulting values for the requested variable.

Interface description for a variable access method (single point).
To obtain values of a given variable, it is necessary to state the space and time at which the variable should be evaluated. The interface is vectorized and provides n values at n different space locations at the same time. Of course the variable system itself also needs to be passed in, to allow the computation of other derived quantities as needed. The method description itself is passed in automatically, and has not to be provided explicitly.
