|
|
* @brief Hyper tree grid level extraction
|
|
*
|
|
*
|
|
* Extract all levels down to a specified depth from a hyper tree grid.
|
|
* If the required depth is greater or equal to the maximum level of the
|
|
* input grid, then the output is identical.
|
|
* Note that when a material mask is present, the geometry extent of the
|
|
* output grid is guaranteed to contain that of the input tree, but the
|
|
* former might be strictly larger than the latter. This is not a bug
|
|
* but an expected behavior of which the user should be aware.
