evaluate_first_spacetime_scalarByTreeID Subroutine

public recursive subroutine evaluate_first_spacetime_scalarByTreeID(fun, varSys, elempos, time, tree, nElems, nDofs, res)

Call the spacetime function for scalar variable, which are stored in method_data which intern points to tem_st_fun_listelem_type. this spacetime function can be used as a analytical solution for reference. note: ndofs is not used by this routine. so, to evaluate spacetime function for ndofs in an element, use tem_varsys_proc_point interface.

\verbatim -- in lua file, one can define it as following: variable = {{ name = 'reference', ncomponents = 1, vartype = st_fun, st_fun = luafun }, ... } \endverbatim

the interface has to comply to the abstract interface tem_varsys_module#tem_varsys_proc_element.
