[edit] Method of lines

Thank you for the Method of lines article. And I have a note. When moving articles, one should use the "move" tab rather than cut and paste, since with the latter we lose track of an article's history. I now merged back the histories of Method of lines and Numerical method of lines. You can reply here if you have comments. Cheers, Oleg Alexandrov (talk) 00:42, 30 April 2007 (UTC)

Oleg: Thanks for informing me. I am somewhat new to wikipedia and am not familiar with the finer points of editing, etc. I will use move in future. Regards Griffgruff 18:52, 4 May 2007 (UTC)
No problem. :) Oleg Alexandrov (talk) 02:02, 5 May 2007 (UTC)

[edit] MUSCL scheme

My compliments for your texts in MUSCL scheme, Flux limiter and more. You added just that little bit of extra understanding to get the bigger picture! On the MUSCL talk page, I added a question, I am not sure whether you are watching that topic, so this is a reminder (no hurry, though) --ArthurVanDam 12:30, 16 May 2007 (UTC)

Thank you for your feedback and kind comments. Griffgruff 11:27, 17 May 2007 (UTC)

[edit] Note on BC

Hi. Thank you for adding references to the boundary conditions articles. One small note: per conventions references should go after "see also", rather than before (I fixed that). I have a comment. I am not sure how widespread the terminology "first type", "second type", etc., is, I have never heard of it. I am not sure if it is worth mentioning it right at the beginning. I removed it for now, but I can add it back if you think it is widely used. Thanks. You can reply here. Oleg Alexandrov (talk) 06:57, 5 January 2008 (UTC)

Thank you for pointing out the convention that References come after See also, and for making the changes. With regard to boundary conditions, there is a convention, albeit not universal, that describes them as:
  • a boundary condition of the first type is called a Dirichlet boundary condition;
  • a boundary condition of the second type is called a Neumann boundary condition;
  • a boundary condition of the third type is called a Robin boundary condition.
However, it does seem to be universally accepted that they are presented in the above order when defining them. I have no particular axe to grind on this although my preference would be for them to be described as first, second and third type.

OK, I put back the "types". Cheers, Oleg Alexandrov (talk) 05:12, 9 January 2008 (UTC)

[edit] Image source problem with Image:Bramvanleer.gif

Image Copyright problem

Thanks for uploading Image:Bramvanleer.gif. I noticed that the file's description page currently doesn't specify who created the content, so the copyright status is unclear. If you did not create this file yourself, you will need to specify the owner of the copyright. If you obtained it from a website, then a link to the website from which it was taken, together with a restatement of that website's terms of use of its content, is usually sufficient information. However, if the copyright holder is different from the website's publisher, their copyright should also be acknowledged.

As well as adding the source, please add a proper copyright licensing tag if the file doesn't have one already. If you created/took the picture, audio, or video then the {{GFDL-self}} tag can be used to release it under the GFDL. If you believe the media meets the criteria at Wikipedia:Non-free content, use a tag such as {{non-free fair use in|article name}} or one of the other tags listed at Wikipedia:Image copyright tags#Fair use. See Wikipedia:Image copyright tags for the full list of copyright tags that you can use.

If you have uploaded other files, consider checking that you have specified their source and tagged them, too. You can find a list of files you have uploaded by following this link. Unsourced and untagged images may be deleted one week after they have been tagged, as described on criteria for speedy deletion. If the image is copyrighted under a non-free license (per Wikipedia:Fair use) then the image will be deleted 48 hours after 00:00, 20 April 2008 (UTC). If you have any questions please ask them at the Media copyright questions page. Thank you. Polly (Parrot) 00:00, 20 April 2008 (UTC)
