How to set the medium and the thickness for one of my faces

CORENTIN Leroy

Hello everybody!

I hope this is the correct place for this topic, otherwise can someone tell me where I can ask?

For my project, I am using Altair FEKO v2018.2 and I decided to automate the process to create my project but I have no clue how can I set the medium of one of my faces.

I tried several ways with the properties Medium and Thickness but all the time this happens :

Error 16628: Error in expression at position 0 for expression: Thickness = 

The problem is when I change the Medium, then I change the thickness (from nil to value) but it doesn't work.

I also know my Feko version is old but I cannot change right now. 

Thanks you by advance for your help!

Hello Torben,

I have already learned how to do it manually but here the problem is doing it with the script editor. I have a lua file and I create a lot of geometries, unions and substracts.

Because I am not working with PEC Medium but with Aluminum, I have to set the properties of my faces (Medium,LocalMeshSize,Thickness...) 

I can change the Medium of my Regions with this lign for example : 

overall_enclosure.Regions[1].Medium = dielectric

But for my faces this is not the same thing because we have to change the thickness also. 

 

The documentation from 2018 doesn't help me for this part and I tried a lot of things but nothing works.

Thank you by advance for your further respond.

Hi @CORENTIN Leroy ,

Please see this script which I just created using the Macro Recording. It creates a new model, add Aluminium, creates a rectangle and applies Aluminium with 1 mm thickness to it.

Hope this helps!

Best regards,
Torben

Hi @CORENTIN Leroy ,

Maybe I misunderstand you, but I would recommend that you use a variable for the thickness of the metallic surfaces, whose value you then simply change.

Does this help?

Best regards,

Yes it is working. I had an issue with how I used my GetProperties and SetProperties. 

Thanks a lot!
