To obtain values of a given variable, it is necessary to state the treeID and time at which the variable should be evaluated. The interface is nDofs values to cover the all degrees of freedoms in the element. Of course the variable system itself also needs to be passed in, to allow the computation of other derived quantities as needed. The method description itself is passed in automatically, and has not to be provided explicitly.
| 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(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 |
