Dear Colleague,

Two minor bugs have been discovered in the Lattice Boltzmann Equation (LBE) code 
of DL_MESO 2.5, both related to writing solute concentrations in Structured VTK 
(XML format) output files.

When running the parallel version of the LBE code in DL_MESO and writing VTK 
files with all fluid properties, the closing tags indicating data array 
definitions are currently missed out for solute concentrations, making the files 
unreadable in VTK software such as Paraview. To fix this bug, replace lines 188 
and 582 in lbpIOVTK.cpp (which should currently be blank) with:

  file<<"<⁄DataArray>"<<endl;

The serial version of the LBE code currently does not calculate the correct 
solute concentrations for its VTK output files that include all fluid 
properties. To fix this bug, replace lines 427 and 798 in lbpIOVTK.cpp with:

  ipos[0] = float(fGetOneConcSite(iprop, ilen));

All of the above bug fixes have been applied to the current DL_MESO release: a 
corrected version may be downloaded by registered users of version 2.5 without 
re-registering and decrypted using the same password. (We otherwise strongly 
recommend that users should apply the changes listed above to their copies of 
the code.)
