Upgrade openFoam from 1.6x to 1.7
Hi people
I search on internet but I don't find the answer to my question:
for upgrade openFoam to 1.7 what I need to do...?

only download and install the new version or I need to do something with the old?

thank you very much:)

Greetings Fabio,

If you already have OpenFOAM 1.6.x installed, then it means you already have the necessary tools to build/install OpenFOAM 1.7.x or 1.7.1, whichever version you may want.

You can have more than one installation of OpenFOAM residing in your Linux box. Just follow the idea explained here: making Opt and Debug available with one command (post #2)
This way you can choose which version you want to use, every time you start a new terminal.

As for installing OpenFOAM 1.7.1 or 1.7.x, just follow the instructions at!

Best regards,

Hi Bruno,

Just a quick amateur question. What are the differences between 1.6.x and 1.7.x? seems similar to me?

Kind Regards,

Greetings to all!

Robert, since you asked directly to me, I'll add to Elvis post:
  • with 1.7.x you will have less bugs than 1.6.x;
  • if you do find bugs, you'll be requested to try 1.7.x first;
  • 1.7.x is a bit more nicely packaged and some solvers have merged into a single one. Others have been renamed/revamped.
  • if you plan on using gcc 4.5.x, you are better off using OpenFOAM 1.7.1 or 1.7.x!
