|

|
||||
* Fix *pimdb/nvt* the only supports the "pimd" and "nmpimd" methods. Fix *pimdb/langevin* only supports the "pimd" method, which is the default in this fix. These restrictions are related to the use of normal modes, which change in bosons. For similar reasons, *fmmode* of *pimd/langevin* should not be used, and would raise an error if set to a value other than *physical*.
|
||||
* Fix *pimdb/langevin* currently does not support *ensemble* other than *nve*, *nvt*. The barostat related keywords *iso*, *aniso*, *barostat*, *taup* are not supported.

* Fix *pimdb/langevin* also has a keyword not available in fix *pimd/langevin*: *esynch*, with default *yes*. If set to *no*, some time consuming synchronization of spring energies and
