<font size=2 face="sans-serif">Hi,</font>
<br>
<br><font size=2 face="sans-serif">thanks for the information and you are
right, there is as binary format in getdp. In my tests, it reduces the
file size to around 70% (perhaps, I did something wrong, I am speaking
of element solution files) of the orignal value (it saves 30% traffic)
and you are right, gmsh is able to handle this binary files. I would be
happy, if the file size can be reduced even more.</font>
<br>
<br><font size=2 face="sans-serif">For example, trying "gzip -6"
reduced the file size to around 20% (this saves 80% of the traffic) of
the original value and several other languages (e.g. python) are able to
handle this file format out of the box, so individual post processing procedures
on getdp solution files can be adapted with minimal effort.</font>
<br>
<br><font size=2 face="sans-serif">Gmsh is able to read gzipped solution
files, but not out of the box. Gmsh extracts the files on the hard disk
(not in memory), so you have to clean the working directory manually afterwards.</font>
