deriveCurrentDensity Subroutine

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

Current density is computed from species momentum stored in auxField array. Current density, J = charge_density*velocity = \rho_e * u = \sum_k z_k F p_k / M_k where p_k is the species momentum


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
