New Features:

  • FEBio can now output directly in the VTK file format. (Use to output febio results to a VTK file instead of the standard FEBio plot file.)
  • Added Yeoh constitutive model for uncoupled solid materials
  • Implemented dynamics for linear truss elements.
  • Added reaction rate for solutes modeled as SBMs for consistency with constant reaction rate for SBMs.
  • Added log variables "EulerX", "EulerY", and "EulerZ" for exporting rigid body Euler angles to the log file.

Improvements:

  • Expanded description of building plugin on windows in developer's manual.
  • Added check for valid rigid body ID in rigid initial conditions.
  • Modified FEPrescribedActiveContractionFiber so that it works better with FEBio Studio.
  • Added check for nodal IDs
  • Updated theory for tied-fluid interface
  • Made output of "damage" plot variable consistent with output of "D" log variable.
  • Nodal IDs are now stored on the mesh when reading feb files and written to the plot file.
  • Improved calculation of multiphasic tangent stiffness by accounting for tangents of referential solid volume fraction with respect to strain.
  • Updated documentation to include description of Yeoh material
  • Added units to material parameters of Holzapfel-Gasser-Ogden materials
  • Added support for creating node sets from part lists when reading the febio input file.
  • Added check to ensure that the parent material of "perm-Holmes-Mow" is biphasic or multiphasic.
  • Added initialization of the "E" parameter of the linear spring material.

Bug Fixes:

  • Fixed issue with restarts that use surface, domain, or model log data.
  • Fixed restart issue for prescribed normal displacement.
  • Fixed some serialization issuess with solutes and tied multiphasic interface.
  • Fixed bug with calculation of stv parameter in FEActiveFiberStress and FEActiveFiberStressUC
  • Fixed issue with "cylindrical" fiber generator.
  • Fixed bug with selection of solute id for Nims reaction rate.
  • Fixed bug where exact_eigen now returns correct eigenvalues for a diagonal matrix
  • Fixed typo in user's manual for coupled MR.
  • Added dllexport to some fecore debug functions.
  • Fixed issue with old solid solver for dynamic problems.
  • Fixed bug with initialization of elastic fiber materials.
  • Fixed issue with output of contact gap log variable for node-on-facet contact interface.
  • Fixed couple bugs in "tied-multiphasic" contact interface.
  • Fixed issue with log output of contact pressure (issue #71).
  • Fixed issue with serialization of item lists and domain maps.
  • Fixed issue with serialization of mesh nodes.
