New Features:

  • Introduced the concept of a "study", which is similar to a task but uses standardized input format, called the "options file" and produces an FEBio report.
  • Added timer for serialization. Several previously un-timed functions are now included in the Update timer.
  • Implemented "max shear strain" log variable.
  • Strain based element erosion criterion
  • Added error to optimization report.
  • Optimization task can now print a summary report of the results.
  • Implemented "fluid coronary outflow" boundary condition
  • Implemented "scaled Jacobian" mesh adaptor criterion.
  • Added "tet-quality" mesh adaptor criterion and plot variable.
  • Added range to "density" parameter.
  • Added Tangent_ShearViscosity_StrainRate member to all visous fluid materials.
  • Implemented some support for nlopt's optimization algorithms.

Improvements:

  • Performance improvements for contact algorithms that make use of octrees (e.g. sliding-elastic).
  • The plot file now stores the filename that was used to create it.
  • Modified the "parameter_sweep" task to a study.
  • Options files for studies now start with febio_study.
  • Had to override writeNodalProjectedElementValues to avoid copying of FEParamDouble.
  • Moved construction of local element list in FEFluidFSITraction from Init() to Activate() so that it is reconstructed after remeshing.
  • Ensured that surface element pointers to elements are correctly re-initialized during hex-refine2d remeshing.
  • Node numbers are now validated when building edges from the input file.
  • Updated Starling parameters' meta. [skip ci]
  • This change is needed to make the reversion of a prior commit on thermofluids remain compatible with the rest of the code
  • Minor changes to the optimization input parameter classes.
  • Modified FEThermoViscousFluid to include up to six FEFunction1D scale factors for temperature-dependent properties in fluids. Modified FENewtonianThermoFluid to take advantage of this feature.
  • Updated build files to include nlopt dependency

Bug Fixes:

  • A bug was fixed in the contact potential distance check
  • Fixed missing header include for strcpy (#92)
  • Fixed problem that was preventing initial velocities from working in explicit solid solver.
  • Fixed problem with "truss stretch" plot variable.
  • Fixed bug in FESlideLineConstraint::BuildMatrixProfile.
  • Fixed bug in evaluating node data record that was assuming one-based indexing of nodes.
  • Fixed bug when displaying relative fluid velocity plot variable in a CFD analysis
  • Fixed inconsistent use and output of FERigidConnected::m_nID.
  • Fixed bug in FECoreBase::FindProperty(const ParamString& prop).
  • Now catching error if node indices in NodeSet are out of range.
  • Fixed issue with FEMaterialPointData::ExtractData that was preventing to find the correct component for some complex material definitions.
  • Fixed compilation errors related to std::filesystem on old compilers
  • Made truss material parameters density and E FEParamDouble.
  • Fixed bug in FEPlotParameter so that it can be used by other domain classes besides FESolidDomain.
  • Fixed problem in xmltool when reading scalar valuator classes.
  • Fixed error in updating tabs in XMLWriter.
  • Fixed buffer overflow on Linux caused by snprintf with bad size arg.
  • Fixed issue with reading nodal loads from old 2.0 format.
  • Added additional checks to avoid crashes exporting log data.
  • Added checks to FEElasticMaterialPoint extraction to prevent crash when exporting log data.
  • Fixed bug in FEHexRefined2D related to material ID not set for elements.
  • Fixed issue with assigning validator to enum parameters.
  • Fixed range of fiber-entropy-chain's n_term parameter.
  • Set initial value for m_N parameter and fixed range for m_term in FEFiberEntropyChainUC.
  • Fixed bug in GetMeshParameter when node is references via fromId function.

Documentation:

  • Fixed typo in CONTRIBUTING.md (#128)
  • Added explanation to user manual about warning generated by FEBio when Holmes-Mow permeability encounters negative pore volume
  • Fixed incorrect specification of fluid flux examples in biphasic analyses in user manual.
