Hi

I am trying to find a safe source to download and install CAxEdit, do you recommend any source?

Thanks

Hi @codev,

Caxedit is no longer supported but it appears like the creator's name was Deepak Sathyanarayan. He commented on one of my videos suggesting that he might revive it someday so that doesn't help you in the near term. This is a bit of a precarious spot to be in but I know that a lot of people ask about this, so I'll take the risk for y'all. 

Someone has pointed out that you can try to access the download page through web.archive.org and download a 30 day trial of the software? I have not tried this and cannot guarantee anything. So try at your own risk:

Why bother going through so many hoops? Someone had created a Notepad++ plugin for Abaqus input files, which I was able to improve upon with little effort. I think you can do the same for LS-DYNA formatted input decks.

 

Another option is to quit using Notepad++ altogether - a bit abrupt, I know. I use VIM; it comes with a baked in plug-in for Abaqus which works for LS-DYNA as well. VIM is a beast, works both in Linux and Windows, is non-intuitive and pain in the neck but who doesn't have a personality? 🙂

@codev if you want don't want to use vim, but still want CAxEdit-like code-folding and syntax highlighting for LS-DYNA input files, use the attached Notepad++ UDL. I used the same color scheme as CAxEdit, but if you follow the instructions in the xml file you can easily change the colors to whatever you like.

To install the UDL just open Notepad++, go to Top Menu -> Language -> User Defined Language -> Open User Defined Language..., and then copy the LSDYNA_UDL.xml file into the folder which opened and restart Notepad++. Now whenever you open a new .k, .key, or .dyn file in Notepad++ it should automatically have the same type of code-folding and syntax highlighting that you have in CAxEdit. To fold all lines use Alt+0 and to unfold all lines use Alt+Shift+0.

@codev sorry I tried to attach the LSDYNA_UDL.xml file to the above post but it seems like the xml filetype is not allowed on this site (any reason why @negativevolume?) so I'll attach it as a plain text file to this post. Make sure to change it to .xml before adding it to Notepad++'s User Defined Languages folder or it won't work.

If @codev is playing with Vim, then here are the steps -

1. Open file in Vim (gVim for Windows)

2. Press Escape on your keyboard (to be sure you are in the right mode)

3. :setf abaqus (colon upfront is essential)

That's it. Code folding/highlighting is enabled for LS-DYNA keyword decks.

You have to do a bit more work to make that the default behavior but I won't go there just yet.

Again, I am not a huge fan of Vim. No sane person can remember the various combinations of keys you have to use to get more than a few basic things done. However, I like it because you can do some powerful stuff with it simply by pressing just a few keys - the trouble, of course, is knowing/remembering those combinations.

@icebreakersours well I'm not going to disagree that vim is powerful (I use it as my default text editor when using the terminal) but I don't like the code folding style it uses for LS-DYNA keyword decks.

By default it uses 2 lines per fold instead of just 1, and it also uses the same color for comments, normal text, and numbers (see attached image for comparison of default gvim with :setf abaqus vs default notepad++ with the LSDYNA_UDL installed).

Also it's not as easy to customize. If I wanted to use my own colors for LS-DYNA keyword decks how would I set them in vim? Well I'd either have to edit abaqus.vim or use it as a guide for creating a LS-DYNA plugin (as the abaqus plugin can't recognise LS-DYNA style comments), and then I'd have to work out how to set the colors I want (looking at abaqus.vim now it is not obvious how to do this). Whereas in notepad++ it is self-explanatory. You either use the gui user defined language editor to select colors or just replace the hex color codes in the xml file.

Style issues aside, when editing just a few fields in a large text file, don't you find it easier to use the mouse to select fields than to use the keyboard?

@chickenandchips very cool integration with notepad++. Sorry about the .xml…the platform I use for this forum automatically blocks certain file extensions and I’ve tried to override them to no avail. 

I’ll continue to try to work it out. Especially since the most common dyna files .k, .dyn are in that blocked list…
