This routine returns value at the given index. If value is pre-computed and value at given index is returned else value is computing on the points for given index.
If a variable has more than one spacetime function, then result is sum of all spacetime functions

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 |
