About FEKO's Temporary Directory

Altair Forum User

Hi.

My simulation is getting larger and FEKO prompted as 'Not enough memory available on the disk'.

So i need to upgrade my hard drive.

I added 1TB hard drive to my computer.

So how can i change FEKO's temporary directory?

Thanks for answers...

Regards...

Hello mustaphos,

 

You need to change your FEKO_TMPDIR by modifying (or adding) the following line to FEKOenvironmentFromSetup.lua:

 setEnv([[FEKO_TMPDIR__SETUP]], [[C:\Temp]], true);

You could also simply define an environment variable FEKO_TMPDIR and let it point to where you want to let FEKO use temporary disk space.

Hello JIF, I had the same problem so I used your suggestion:

So I changed the temp directory to my D drive as it has a lot more space.

 

To this, I got the following error:

ERROR 33867: Error (-3) checking/creating temporary directory at \Temp\

 

Any ideas on how to fix this?

 

Thanks

From the error message, it sounds like \Temp does not exist. Have you tried creating that directory? Or does it already exist?

Hello JIF,

 

I had created the temp directory, just had to restart the model for it to pick up the new TEMP directory location. 

 

Thanks!

Just use notepad to edit the FEKOenvironmentFromSetup.lua file in the 'feko' folder.

Save it. All new instances of Feko will use the updated file.

@melcan you explain more how can i use notepad in feko folder?

Mel

Copy the file to e.g. C:\Temp

Edit there.

Copy back, but you will need admin rights.

Alternately you can set this and other environment variables in CADFEKO:
