  • Status changed from new to accepted

To test use convertUnits, also check out the unit tests in kernel\unittest.h

The emode must be set to elastic, and efixed holds the constant value (provided by the scientist).

Thanks Nick,

Looks like it works fine. Black is the new conversion and red my old one. Thanks to whoever did such a quick job.
