Same as division_forElement except it division values from points via indices which are setup before
The interface has to comply to the abstract interface tem_varSys_module#tem_varSys_proc_getvalofindex.

| Type | Intent | Optional | 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(tem_time_type), | intent(in) | :: | time |
Point in time at which to evaluate the variable. |
||
| integer, | intent(in) | :: | iLevel |
Level on which values are requested |
||
| integer, | intent(in) | :: | idx(:) |
Index of points in the growing array and variable val array to return. Size: nVals |
||
| integer, | intent(in), | optional | :: | idxLen(:) |
With idx as start index in contiguous memory, idxLength defines length of each contiguous memory Size: nVals |
|
| integer, | intent(in) | :: | nVals |
Number of values to obtain for this variable (vectorized access). |
||
| real(kind=rk), | intent(out) | :: | res(:) |
Resulting values for the requested variable. Dimension: n requested entries x nComponents of this variable Access: (iElem-1)*fun%nComponents + iComp |
