This routine prepares the data for variable derivation or operators. It gathers all input variables from the variable system, calls the function with the actual calculation.
| 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. |
||
| integer, | intent(in) | :: | elempos(:) |
position of the treeid of the element to get the variable for in the global treeid list. |
||
| type(treelmesh_type), | intent(in) | :: | tree |
global treelm mesh info |
||
| type(tem_time_type), | intent(in) | :: | time |
point in time at which to evaluate the variable. |
||
| integer, | intent(in) | :: | nVals |
Number of values to obtain for this variable |
||
| procedure(mus_derive_fromPDF), | pointer | :: | fnCalcPtr |
Function pointer to perform specific operation. |
