General Questions and Answers / Device calculation for collinear electrodes

« on: January 27, 2021, 06:02 »

Dear Sir/Madam,

I want to do device simulation for concentric tubes. Where, my innermost and the outermost tubes act as electrodes. But, I have not been able to carry out the same as for a device simulation, the two ends are automatically considered as electrodes depending upon the size defined by the user.

Hence, could you please help me in this regard.

Thank You.

General Questions and Answers / How to build a MTJ device with different oxide 'stack'?

« on: April 6, 2017, 09:17 »

I wish to build a MTJ device for certain simulation and tried using the existing plugin of Fe-MgO but I couldn't build one with a different oxide 'stack' as only single oxide layer was possible. How do I replace the oxide with a oxide 'stack' of different combination.

Installation and License Questions / Why does VNL requires me to configure the license everytime I start it.

I have an annual license and a perpetual license for ATK and have duly configured the licenses as per the instructions but why does it ask for license every time I start VNL. There is also the error message every time I try to provide the link of the license.

I am hereby attaching the screenshot of the error. I have been trying by all means to overcome it, but its not happening. I have also tried checking the firewall and other network settings but none has worked yet. Although some days back i had been able to access the database and build a structure.

Thank you Sir for your kind response. But i am still not able to connect to www.crystallography.net when requesting for the database. Is it due to some connection problem from my end but it was fine few days back and i had got some work done too then. Also when i am trying to connect to the site directly from the browser its opening.
But i am not able to get the elements and compounds that i need on VNL ATK.

Dear Sir / Madam,

This is in continuation to my previous query. I had been able to use elements and build structures  from Crystallography Open database. But today i am not able to reach Crystallography Open database website and get a structure. Is it a problem of my software or the website is down so that i am not able to reach it.
