As of version 1.3 FEBio supports a new plot file format. The format was designed to overcome the limitations of the old format. In particular, the new format has a flexible structure that supports backward compatibility and is extendible. This implies that the user has complete control over its contents and can choose which variables go into the plot file. The format is fully integrated with FEBio's supporting software as well: PreView will request the new format by default and PostView supports it.

For developers who want to dissect the plot file, a document was prepared which details the contents. Attached a first draft of this document is available. If you have any questions or have some suggestions or comments, feel free to share them with us.
