Dear Colleague,
 
Some minor updates to DL_MESO 2.7 have been made and are now available for 
registered users to download as a revised version of the package (2.7 rev 08). 
You do not need to re-register for this update if you have previously 
registered for an earlier form of version 2.7: the revised package can be 
downloaded from the same location as before and decrypted using the same 
password. If you would like to use version 2.7 but have not yet registered for 
this version (e.g. if you have previously registered for version 2.6), please 
do so via the link from the DL_MESO website at www.ccp5.ac.uk/DL_MESO
 
Changes made to DL_MESO include corrections to reading CONFIG files in the DPD 
code to ensure correct detection of numbers of particles and their species, 
omission of many-body DPD self-potential terms for pairs of frozen particles, 
corrected shear rate calculations when using Two-Relaxation-Time (TRT) 
collisions for non-Newtonian rheological models and a minor bug fix in 
reporting fluid densities during LBE calculations with Swift free-energy 
interactions. Other minor changes include clean-ups of the main DPD and LBE 
codes and their utilities to remove extraneous variable declarations and the 
addition of OpenMP multithreading for many-body DPD self-potential calculations 
when using this form of the DPD code. Updates to one of the DPD test cases 
(SurfaceDrop), the user manual and README files have also been made. (Many 
thanks are due to David Gunn at UKRI STFC Daresbury Laboratory for highlighting 
the CONFIG file reading issue.)
