Task Introduction#
Currently OpenMC supports two types of variance reduction (survival biasing and weight windows). A detailed description of each method can be found in the documentation.
OpenMC also supports methods of generating weight windows including the Magic Method and FW-CADIS
The notebooks contain all the methods for completeness, however ff you just have time to learn one method then I would recommend the FW-CADIS approach.
The workshop contains the following variance reduction examples:
