  • Several issues with the cold restart capability were addressed.
  • An issue was caused that could cause a crash when rigid rotational dofs are coupled to a biphasic element.
  • Added dump stride parameter, which allows users to specify how often the dump file is written.
  • Added "contact_traction" log variable.
  • Added names of parent when printing model parameter values.
  • Support for the MKL-DSS solver was added, which seems to work better for certain types of models than the default pardiso solver.
  • Added gap offset option to facet-2-facet sliding.
  • Fixed issue with plot output logic when first step does not request output.
  • Fixed bug in "element center of mass" plot variable.
  • Parameters of "orthotropic elastic" material can now be mapped.
  • Added "discrete element signed force" plot variable.
  • Added log variables for discrete element force components.
  • Fixed bug in compressible Gent material.
  • Added "facet area" log variable.
  • Added "deformation gradient" plot variable.
  • Fixed issue with initialization of FEParamMat3d parameters.
  • Added FEMathExpression that refactored some of the logic previously in FEMathValue. FEMathValueVec3 now also uses FEMathExpression so that it can support maps.
  • Added prescribed fiber active contraction models. (Similar to uniaxial, but fiber direction can be defined by user.)
  • Added support for mixture stress log variable.
  • The "mixture stress" plot variable now also works for uncoupled mixtures.
  • Fixed calculation of fixed charge density in multiphasic and triphasic materials (in FEBio3)
  • Added error exception in Holmes-Mow permeability to catch pathological case.
  • Added "contact area" log variable.
  • Updated Theory Manual to fix calculation of fixed charge density in reactive multiphasic materials that use charged solid-bound molecules
  • Added description of fluid RCR surface load in User Manual
  • Fixed the fluid RCR surface load and made it ready for release. Simplified the fluid resistance to be consistent with fluid RCR.
  • Allow the initial referential mass density of solid-bound molecules, m_rho0, to be a FEParamDouble.
  • Updated FEMembraneMassActionForward and FEMembraneMassActionReversible to use areal concentration of solid-bound molecules. Updated FEMembraneReactionRateIonChannel to accommodate solid-bound molecules in the calculation of the reaction rate.
  • Added exponential damage CDF (useful for reactive viscoelastic materials with exponentially increasing weak bond fractions with increasing strain)
  • Added aggressive interpolation type as user-specifiable option in BoomerAMG solver.
  • Modified FEFiberPowLinear and FEFiberPowLinearUncoupled to use FEParamDouble material coefficients.
  • Updated FEIdealGasIsentropic and FEIdealGasIsothermal to run properly in current version of FEBio.
  • Point Source Updates
  • Fixed bug in FEContinuousFiberDistribution::Stress
  • Fixed issue with exporting plot parameter for mapped parameters of nodal loads.
  • Added support for X, Y, Z in generic hyperelastic material.
  • Restricted nodal reaction forces plot variable to non-rigid materials.
