FEBio 3.4

• This version has an updated EULA (EULA version 4). This EULA adds a PRIVACY clause that details how and what information the software (i.e. FEBio Studio) communicates with an external server.
• On Windows, this version was built with a newer version of Visual Studio (Visual Studio 2019). As a result, a new SDK has been released and it is highly recommended to rebuild any plugins against this new version.
• A bug was fixed for shells that are directly attached to rigid bodies (i.e. shells that share nodes with rigid bodies).
• The formulation of strain energy density for fiber-pow-linear-uncoupled material was fixed. In addition, a bug was that which produced discontinuous stress and elasticity at transition from toe region to linear region. The user manual was updated to reflect these changes.
• A bug was fixed in CMakeLists that caused an error on Windows if not using MKL.
• A bug was fixed in the "porosity" element log variable.
• The description of the max_retries control parameter in the user manual was corrected.
• The "reaction forces" plot variable now produces the equivalent nodal reaction forces for all nodes, even constrained nodes (fixed, prescribed, rigid).
• Chapter on multi-step analysis was added back to user manual and several broken links were fixed.
