Learning Forum

[Chris Kopetski]

Lumerical community support moved from the Lumerical Knowledge Exchange (KX) to the Ansys Learning Forum (ALF) on April 16, 2021. This move is part of ongoing efforts to integrate Lumerical products and services with the rest of the Ansys organization. We?re moving to a new site, but Lumerical?s team of Application Engineers will continue providing support to our customers. That said, there are a few important differences to understand. nYou?ll have to create an ALF account. After that, go to the Photonics category and ask (or answer!) a question. Lumerical?s support registration is not required to access ALF.nCheck out the Guidelines for posting on the Ansys Learning Forum. A key difference between ALF and KX is that Ansys employees (including the Lumerical team) are not permitted to download any attachments (learn more here). Screenshots are recommended if you want feedback on the settings in your project files.nIf you have trouble creating an ALF account, contact us here. Pick the 'Account Inquiry' option and state that you are having trouble creating an ALF account.n

Hello,nWhere is all past lumerical forum threads material going to be moved? It would be not be particularly nice if all the support material already existing on kx was trashed...I also lost access to all my previous enquiries on the forum and the related answers, which in some cases were half-way and not fully answered yet.n

Hi,nSo where can I found the previous posts on KX ? n

[Chris Kopetski]

Many of the ~400 topics in the Photonics section of ALF are posts that we have migrated from the Lumerical KX. We prioritized the topics to move based on their popularity (i.e. page views) of each topic. Lumerical staff will still have access to the KX content for a few more months, and will continue to migrate more content to help answer new questions that are asked in ALF. nOur original plan was to move all of the KX topics (>10,000) to ALF, but unfortunately that was not feasible. n: If your discussion was interrupted by the switch to ALF, please re-post your question.n

[tiach329]

Even topics with little popularity on KX may be helpful to many users. So why can't you keep the KX only being accessed and close other functions, like posting and editing? n

Hi,nalso in my opinion all the posts on KX are critical for many users. My work already is compromised by the fact, that I can notquicklylook up small issues. These are problems for that it is often not feasible to post a new question every time. KX was able to immediately provide answers. Without this feature, the software losses a lot of quality.n

[Chris Kopetski]

I apologize for the disruption this change has caused to everyone. The best I can offer is for you to re-post your question in the Ansys forum. If it was already answered in the KX, we should be able to provide a faster reply. I realize that's not as quick as simply searching for existing content, but over time the Ansys forum gain more and more content, and hopefully offer a similar experience to the old Lumerical KX.n

ArrayYeah.. I also strongly believe this. Whatever I am currently searching in Lumerical KB it is suggesting to use ANSYS learning forum and these informations are not available in ansys however it is showing in google partially. This is giving too much problem. Ansys should have planned before making any decision on the forum side. n

[Chris Kopetski]

Thanks for the feedback. While we are not able to bring the old KX back, the comments from everyone in this thread show that it's worthwhile for us to continue migrating content from the old KX to ALF. n

[mustafacc]

Is it at least possible to see the posts that our old usernames contributed to? I've had a few example scripts and workarounds to many issues I was having attached to posts and replies that are quite obscure. I always used to refer back to those threads to look up the solutions. n

Hello!nI know that at the moment Lumerical kx is not available, but I'm looking for an answer of certain question and it looks like it has already been dicussed here https://kx.lumerical.com/t/example-how-to-track-a-specific-mode-profile-for-variable-structure-dimensions/6546. Could you please help me to get acces to this link or to move all discussions to the AVF? It's crucial to my work.n

[Chris Kopetski]

Normally I would move your posts to ALF so others could benefit from what you shared. However, Ansys staff are not allowed to post example files (details here, here), so I can't re-post the files you shared. I've sent you an email with the information contained in your old posts. You're welcome to re-post on ALF, but it's totally up to you.n

[Chris Kopetski]

That page will be moved to https://support.lumerical.com/hc/en-us/articles/1500006158142. It's not ready yet, but should be available in the next few days. n

Hi there, I'm looking for an answer of certain question and it looks like it has already been discussed in the below link. Could you please help me find the answer to my question? Thanksnhttps://kx.lumerical.com/t/how-to-simulate-the-charge-distribution-with-unpolarized-light/9951n

It doesn't seem like this decision was made with the users best interests in mind. After working with lumerical for some time, I have a collection of frequently visited links which are critical to many aspects of the work I do, these are now useless. Furthermore, with out the KX I can say the success of my projects would have been much delayed as it is a vital tool for simulation set up and troubleshooting. Ansys has created the perfect opportunity for users to start thinking about whether or not this is time to start migrating to a different software, given that a critical aspect of the support has been removed on top of the typical frustrations of working with lumerical. nIt would be within the users best interest to have the old KX available until everything has been fully migrated to the new forum. At the very least, for the old links to redirect you to the topic now on the Ansys forum. Not to mention the amount of time employees will have to spend answering the same questions which they have already provided comprehensive answers to...(on top of all the work they are putting into migrating old inquiries).nAn unnecessary duplication of everyone's efforts and poorly thought out migration plan. Thanks Ansys.nn
