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, Mac OS X,
|
|
and Microsoft Windows 7. Memory requirements will vary depending on the size of
|
|
the problem at hand (mostly on the number of nuclides in the problem).

New Features
|
|
------------
|
|
|
|
- Ability to specify void materials.
|
|
- Option to not reduce tallies across processors at end of each batch.
|
|
- Uniform fission site method for reducing variance on local tallies.
|
|
- Reading/writing binary source files.
|
|
- Added more messages for <trace> or high verbosity.
|
|
- Estimator for diffusion coefficient.
|
|
- Ability to specify 'point' source type.
|
|
- Ability to change random number seed.
|
|
- Users can now specify units='sum' on a <density> tag. This tells the code that
|
|
the total material density is the sum of the atom fractions listed for each
|
|
nuclide on the material.
