+
+ The computation enables fast parallel localization, and is based on a point in element search, followed
by a field evaluation at the point location. Thus, it is typically
- faster than the \ref intersectiondec which gives a \ref conservativeremapping.
- It is particularly true for the initialisation phase (synchronize)
- which is very computationnaly intensive in \ref intersectiondec.
+ faster than the \ref InterpKernelDEC-det "InterpKernelDEC" which uses a
+ \ref InterpKerRemapGlobal "conservative remapping" (i.e. the same algorithms of volume
+ intersection as in the \ref remapper "sequential remapper")
+ It is particularly true for the initialisation phase (synchronize() method)
+ which has a significant computation cost in \ref InterpKernelDEC-det.
- In the present version, only fields lying on elements are considered.
+ In the present version, only fields lying on elements ("P0") are considered.
The value is estimated by locating the barycenter of the target
side cell in a source cell and sending the value of this source cell
as the value of the target cell.
