New Features:

  • The "CG-solver" now supports preconditioners (#67)
  • Added fluid supply function to biphasic-FSI materials.
  • Added Starling fluid supply constitutive model for biphasic-FSI fluid supplies.
  • Implemented nrrd image reader.
  • Added support for storing global data in plot file. By default, PID controller values are now stored to the plot file.
  • Added "mesh_data" plot variable, which allows storing mesh data in the plot file.

Improvements:

  • Added support for reading part lists from feb4 file.
  • Improved error detection in fluid dilatation calculation of the "real vapor" material.
  • Added check for node ID numbers in linear constraints.
  • Updated default analysis type for biphasic analyses to be TRANSIENT.
  • The "m" parameters of Ogden materials now support maps.
  • Added support for reading vector of strings as xml tag.
  • Modified default settings for biphasic-solute and multiphasic analyses to be TRANSIENT (instead of STEADY-STATE).
  • Added units for coefficients c1 and c2 of Mooney-Rivlin materials that were missing them.
  • Added units to velocity in fluid normal velocity.
  • Added documentation on CG-solid solver.
  • Added error message when a fixed constraints has no dofs fixed.
  • Now, storing initial line coordinates of line object.
  • Updated some plot variables that were not thread-safe.
  • Added support for domain data stored as FMT_NODE.
  • The Surface-to-surface map is now evaluated at the nodes so that it can be replicated more accurately in a plot variable.
  • Updated error message when the fiber property of a material cannot be found when parsing ElementData section.
  • Added support for .fiber variable in ElementData. (which allows the "old" way of assigning user fiber data to mixture components.)

Bug Fixes:

  • Fixed bug in assembling stiffness of linear constraints.
  • Fixed bug with assigning maps to array parameters.
  • Fixed issue with model reset.
  • Fixed issue with attributes getting processed twice.
  • Fixed issue with default name for line objects.
  • Fixed issue with initialization of rigid body COM so the correct values are available for PID controllers that reference these parameters.
  • Fixed bug in "fluid surface force" plot variable to update surface area and surface normal at each time point, producing correct results for fluid-FSI problems. Fluid problems not affected.
