getElemWeight Subroutine

private recursive subroutine getElemWeight(fun, varSys, elempos, time, tree, nElems, nDofs, res)

Get the computational weight of elements

Arguments

Type IntentOptional Attributes Name
class(tem_varSys_op_type), intent(in) :: fun

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.
type(tem_varSys_type), intent(in) :: varSys

The variable system to obtain the variable from.
integer, intent(in) :: elempos(:)

Position of the TreeID of the element to get the variable for in the global treeID list.
type(tem_time_type), intent(in) :: time

Point in time at which to evaluate the variable.
type(treelmesh_type), intent(in) :: tree

global treelm mesh info
integer, intent(in) :: nElems

Number of values to obtain for this variable (vectorized access).
integer, intent(in) :: nDofs

Number of degrees of freedom within an element.
real(kind=rk), intent(out) :: res(:)

Resulting values for the requested variable.

Linearized array dimension: (n requested entries) x (nComponents of this variable) x (nDegrees of freedom) Access: (iElem-1)fun%nComponentsnDofs + (iDof-1)*fun%nComponents + iComp
