## Bug #1244

### cos-acceleration viscosity output incorrect

Affected version - extra info:

uncategorized

**Description**

The viscosity output with cos-acceleration is off by a factor of the box volume.

For version 4.5.4 I ADDED a missing factor of density instead of REPLACING the volume.

Note that the incorrect viscosity value you get can be simply corrected by dividing by the box volume.

### Associated revisions

fixed incorrect scaling of cos-acceleration viscosity

The cos-acceleration 1/viscosity output contained an anomalous factor

1/volume. This factor is now removed.

Fixes #1244
