New license server 4.9

Dear all,

we have managed to install the new license server. Its version is 4.9.

The accounts are not yet created. I'm looking for one or two peoples who agree to be admin and manage the accounts creation on the license server. The work is pretty simple, but it's important to remove account when people/students leaves EPFL or finished courses. Any suggestions are welcome on how to manage that. For now, I propose that people who want an account comments this post: account name, want to be admin or no, expiration date of account.

Some quick updates:

  • install vali in c:\belsim
  • vali username have to be the same of the windows username (no admin, administrator, administrateur account allowed!)
  • people belonging the the vali groups on can access the installation files on in the folder vali (for 4.9 it's
  • and the most important the new license server is "". If you are not installing a newest version of vali you have to change that in the Belsim.ini file.

I quicky test the gas turbine and it works. Another (more complex) tests would be apreciated.

vali 4900


When more tests are accomplished, the wiki page will be updated.

In case of question please do follow How To Get Help.

Best regards,

The same units for different measurements on the same stream give different values. With VOLF Nm3 is not taken into account, it is really m3.

This is with Vali I am not sure why, but I just thought I'd share.

valitauto had a problem


I updated to Vali 4.7+ (one little step at a time). Ever since when I run Vali through Osmose... I get a window that says : "valiauto.exe had a problem and needs to be closed. Send a report error to windows". And I need to close that window or will not get to the next point....

Before I contact the support, has anybody had the same problem and knows how to fix it?
