System Requirements
|
|
-------------------
|
|
|
|
There are no special requirements for running the OpenMC code. As of this
|
|
release, OpenMC has been tested on a variety of Linux distributions as well as
|
|
Mac OS X. However, it has not been tested yet on any releases of Microsoft
|
|
Windows. Memory requirements will vary depending on the size of the problem at
|
|
hand (mostly on the number of nuclides in the problem).

New Features
|
|
------------
|
|
|
|
- The probability table method for treatment of energy self-shielding in the
|
|
unresolved resonance range has been implemented and is now turned on by
|
|
default.
|
|
- Calculation of Shannon entropy for assessing convergence of the fission source
|
|
distribution.
|
|
- Ability to compile with the PGI Fortran compiler.
|
|
- Ability to run on IBM BlueGene/P machines.
|
|
- Completely rewrote how nested universes are handled. Geometry is now much more
|
|
robust.
