I use a software package called OrcaFlex for modeling marine structures. It has extensions in MATLAB, Python, and C (I use MATLAB) that are used for setting up the models and retrieving and analyzing the model results. Setting up the models requires a lot of tricky choices that would be nice to discuss with others, but the only choice is emailing the (very helpful) support staff, or posting questions to the software developer's blog. Is there a place on Stack Overflow or related sites that would be an appropriate place start posting questions about use of OrcaFlex? Or is the software too specific to marine engineering? There are no existing OrcaFlex questions on Stack Overflow.
Welcome to Stack Exchange, KAE! If you're doing programming of some kind, like improving the code of OrcaFlex itself or developing a plugin, then use Stack Overflow. If you're just trying to figure out how to better use the program, try Super User.
We won't consider your question unacceptable for being "too specific to marine engineering" (or any given field), but if there are no other OrcaFlex users visiting our sites, you may not get answers.
