Hello, colleagues!

Please explain me the following. Is it possible to have installed OF-1.6 and OF-1.5-dev on one PC simultaneously?
Now I have OF-1.6 installed and I would like to use some OF-1.5-dev features. I tried just to copy some source files to OF-1.6 src directory but these files failed to compile.

Best regards, Aleksey.

Yes Aleksey, you can install either version and switch from 1.6 to 1.5-dev. To use OF 1.6 you must uncomment the line in your .bashrc file

. $HOME/OpenFOAM/OpenFOAM-1.6.x/etc/bashrc
#$HOME/OpenFOAM/OpenFOAM-1.5-dev/etc/bashrc
#export PATH=$PATH\:$HOME/OpenFOAM/OpenFOAM-1.5-dev/wmake

and to use OF 1.5-dev uncomment the other two

#. $HOME/OpenFOAM/OpenFOAM-1.6.x/etc/bashrc
$HOME/OpenFOAM/OpenFOAM-1.5-dev/etc/bashrc
export PATH=$PATH\:$HOME/OpenFOAM/OpenFOAM-1.5-dev/wmake

After every changes remember to type, in a terminal, the command:

source ~/.bashrc

Sincerely,
Alex

Hi Aleksey,

I have the same setup, but if you get bored with opening .bashrc, editing, saving, and sourcing it, you could use an alias for each version. I have the following in .bashrc:

## Source OpenFOAM-1.5-dev
alias dev='. $HOME/OpenFOAM/OpenFOAM-1.5-dev/etc/bashrc'

## Source OpenFOAM-1.6.x
alias 16x='. $HOME/OpenFOAM/OpenFOAM-1.6.x/etc/bashrc'

So, when I want a certain version of OF I just type the alias (in this case "dev" or "of16") in the terminal and it works .

Thanks for help, gentlemen!

And what version of paraview and other third party programs do you use? From 1.6 installation or from 1.5-dev?

[gwierink]

I use ParaView-3.4.0 via VTK because that is at the moment the most stable on all my machines (but that's mainly a graphics card issue on my work laptop ... ).

I'm involved in ship hydrodynamics and, starting from OF 1.5-dev version I'm migrating to OF 1.6, either with ParaView 3.6.2 with vtkPOpenFOAMReader plugin.

Axl,

Did you already make a good ship simulation with OF-1.6. In this thread (http://www.cfd-online.com/Forums/ope...ip-flow-3.html), some specialists decided to go back to 1.5 or 1.5-dev, because they had a lot of errors in 1.6.

Now I never use OpenFOAM becouse error over CT are bigger than Fluent, I continue my study with Fluent waiting improvement in future OpenFOAM release. However, during my spare time I try to improve my OpenFOAM case setup... waiting for good news.
