Abstract Interfaces

abstract interface

  • public subroutine atl_derive_fromModalData(fun, varSys, tree, iElem, elempos, nodalInput, nodalRes)

    This interface describes the arguments to be used for routines that do the derivation of variables from the variable system. These derive routines are passed to atl_derive_getElement via a procedure pointer.

    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.
    type(treelmesh_type), intent(in) :: tree

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

    The Current element index
    integer, intent(in) :: elempos(:)

    TreeID of the element to get the variable for.
    type(atl_derive_inputVar_type) :: nodalInput(:)

    The input data. nodalInput contains one entry for each input variable. This entry itself contains the nodal data for the dofs and components of the input variable. These nodal data has to be gained by oversampling and projecting the modal state into nodal space.
    real(kind=rk), allocatable :: nodalRes(:,:)

    The result in nodal space

Derived Types

type, public ::  atl_derive_inputVar_type

This type stores the state data for a given variable and a given element. This type is used to allocate arrays for arbitrary variable counts, as jagged arrays are not allowed in Fortran.

Subroutines

public recursive subroutine atl_generic_fromModal_getElement(fun, varSys, elempos, time, tree, nElems, nDofs, fnCalcPtr, solverData, res)

This routine prepares the data for variable derivation or operators. It gathers all input variables from the variable system, oversamples and projects them into nodal space, calls the function with the actual calculation and projects the results back into modal space. As these projections are common to all elementwise variable accesses, this generic routine does all necessary operations in a generic way.

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(:)

TreeID of the element to get the variable for.
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. Careful: This argument determines how many dofs is returned in the output of this routine
procedure(atl_derive_fromModalData), pointer :: fnCalcPtr

Function pointer to perform specific operation. Sets in routine which calls this routine
type(atl_varSys_solverData_type), intent(inout) :: solverData

Solver data container
real(kind=rk), intent(out) :: res(:)

Resulting values for the requested variable.
