extract_forElement Subroutine

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

Extract component index of any vectorial variable. In lua file, first define new variable with varType operation kind as "extract" and provide name of the variable from which to extract component index via input_varname (it must be single variable) and index to extract via input_varIndex. If input_varname variable is not part of predefined solver variables then add also that variable via variable table.

\verbatim -- in lua file, one can define as following: variable = {{ name = 'vel_y', ncomponents = 1, vartype = "operation", operation = {kind='extract', input_varname={'velocity'}, input_varindex = {2} } }, } \endverbatim

The interface has to comply to the abstract interface tem_varSys_module#tem_varSys_proc_element.


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
