Can EDEM be used simultaneously on two computers?

Hello everybody,
EDEM-Fluent is running in workstation now. I want to check something in my laptop's EDEM simulation. I wanted to run EDEM but it is not possible. I saw the attached error:

Hi Fatemeh,

It depends on your license type. If you have a student license then this is node locked and will only run on one machine.

If that was the case then you would need another license for the second machine.

For other license types EDEM will be pointed towards a license server which has a set number of units.

You can use EDEM on different machines and they can pull licenses from the same server, if this is the case then it looks like you have used all the units through the first machine and there are non left over for the second.

Thanks Stephen.
I looked through the Altair License Utility, but I couldn't see a part where I could limit the amount of units.
Would you kindly advise me?

Hi Fatemeh,

Just to confirm you are not on the student license option? If so then on page 14 of the PDF it shows the EDEMGUI feature and if running this as a desktop application (not batch/command line) then EDEM would take 21 units.

The message you have is 'unable to checkout solver' license which the solver in-app licensing is shown on page 29 and 30. EDEM on 4 CPU's would take 50 units and would take 60 units on 16 CPU's for example. GPU counts the same as 16 CPU's for units so running a GPU simulation takes 60 units.

There is in addition a decay function if multiple jobs of the same solver are running off the same license server, this is shown also on page 30 which would reduce the unit count slightly.

The Altair license utility shows how many units are taken from a given server - https://help.altair.com/hwdesktop/altair_help/topics/tools/altair_license_utility_launch_t.htm
