inline |
Contruct a Const GridFunction.
gv | The GridView to use. It is passed as a reference to AnalyticGridFunctionBase (look there for the requirements of this argument). |
val_ | The value tu return on evaluation. This class stores a copy of that value. |

inlineinherited |
Return the data set type of this function.

Evaluate the GridFunction at given position.
Evaluates components of the grid function at the given position and returns these values in a vector.
[in] | e | The entity to evaluate on |
[in] | x | The position in entity-local coordinates |
[out] | y | The result of the evaluation |
|
inline |
evaluate the function globally
x | Position in global coordinates where to evaluate. |
y | The resulting value. |

set time for subsequent evaluation
This method sets the time for subsequent calls to any of the evaluation methods.
