OpenVSP

OpenVSP can read and write files representing many kinds of information. Some of those representations can be stored in multiple file formats. Some kinds of I/O can only be done through the GUI, but many of the files may be written from the command line.

Although this flexibility makes OpenVSP very powerful, it can be rather confusing for new users. These pages should serve to guide the new user through the kinds of information VSP can read and write.
