FEBio Studio 2.4

New Features:

• Added option to the import-spring tool to generate linear truss elements instead of springs.
• Added support to the import-springs tool to read springs from a vtk file.
• Implemented GMesh (version 4) file export.
• Added option to fiber generator tool to create a map, instead of assigning to element fiber vectors.
• Added additional plane rotation parameters to fiber generator tool.
• Added new geodesic-curve create tool, which can be used to generate geodics, or shortest-path-curves on existing geometry.
• Added filter to convert element data to node data for types vec3f, mat3fs, and mat3f to the Data tab on the Post panel.
• Implemented Kinemat tool on the build side, which allows users to use kinematic data to setup a forward FE model.
• Added panel to Statistics window that shows min, max, mean, std. dev, and std. error.
• Added option to VTK-export to write the element part IDs as cell data.
• Added "Magnitude" component to mat3d and mat3f data types when visualizing FEBio plot data.
• The muscle-paths plots now support a "guided-mesh" feature, which allows the muscle path to move with the deformation of another mesh.
• Added a legend bar for visualizing data using the mesh inspector.
• Added ability to use the plotted data in a math expression in the Math plot tool of the graph window. (use _data as function name.)
• Added support for 32-bit signed and unsigned pixel types for reading 3D image data.
• A new tool was added for editing mesh data on the Tools panel of the Build panel. This tool allows you to overwrite values assigned to elements.
• Added option to write face and element connectivity when exporting data fields from the Post-Data panel.

Improvements:

• Made the Revolve Faces tool more robust.
• Expanded support for reading GMsh 4 files.
• Modified shell thickness modifier so that when no elements are selected, the thickness of all elements is set.
• Added smoothing option to loft tool.
• Nodal and element IDs are now serialized and preserved when writing feb files.
• Node, element, and part IDs are now read from LSDYNA model.
• Added support for reading node IDs from xplt file version 3.3.
• Current folder is now set to the path of the last file that was loaded successfully.
• Added additional support for interpolating state data.
• About box shows normal size FEBio Studio icon again.
• Added scale factor to curve probe. Fixed issue with evaluation of time-averaged data.
• The data import dialog is now used to import the points of the curve probe.
• Ensured that the default directoy for opening and saving is consistent (and equal to the current working directory).
• Added context menu for deleting named selections.
• Added the divisions and smooth options to the legendbar options dialog.
• Use ctrl or ctrl+shift to zoom a plot in x or y only.
• The "Source" label in the Graph window is now hidden when the data source widget is not used.
• Load controllers can no longer be deleted if they are being used in the model.
• Changed the element selection logic so that it is easier to select discrete elements.
• Added support for editing scalar part data stored as DATA_MULT.
• Updated selection report to include nodes of currently selected discrete element.
• Increased the max number of geometry items that can be displayed in model tree to 10,000.
• Ensured that node partitioning remains preserved when partitioning elements.
• Turned off specular lighting when rendering planecut.
• Elements that are visible because neighbors are hidden can also be region-selected with "ignore interior" option on.
• Modified help section on Inflate tool in FEBio Studio User manual.
• Modified Inflate tool for creating boundary layer meshes on existing tetrahedral meshes. The new formulation performs a series of operations that extrude the selected surface inward with a biased mesh, then fills the resulting inner surface with a tetrahedral mesh (TetGen), finally welding the two parts together and returning a rebuilt mesh with no seams.

Bug fixes:

• Fixed crash in mesh inspector when no object is selected.
• Fixed issue with verifying nodal IDs when export to febio file.
• Fixed bug in code that maps parameters between containers.
• Fixed empty error message.
• Fixed shell-to-solid rendering option.
• Fixed bug in option to replace contact interface.
• Fixed crash in Abaqus reader.
• Fixed potential crash in GModel::ValidateNames.
• Fixed some issues where node and element indices were used instead of IDs.
• Fixed issue in reading session files with plot groups.
• Fixed parameter name for muscle path.
• Fixed issues with adding new states. Added support for interpolating data for new states.
• Fixed issue with curve probe parameters not updating. Arc lenghts are now used as the ordinate axis in the curve probe plots.
• Fixed typo in job run message box.
• Fixed bug with Average Intensity Over Elements option in ImageMapTool
• Fixed logic bug in processing error string from lsdyna import.
• Fixed bug in scalar field tool when generating constant element data.
• Fixed issue with importing gmsh file where wrong tag was used to partition the mesh (issue #71)
• Fixed issue with update of the isosurface plot when users change parameters.
• Fixed issue with exporting node sets based on part lists.
• Removed duplicate manual figures
• Fixed issue with volume rendering 32 bit integer images.
• Fixed issue with reading very large Tiff files.
• Fixed crash when exporting a model that has no materials to feb4 file.
• Fixed GUI slowdown caused by working with medium to large images.
• Fixed issue with syncing discrete selection to model tree.
• Fixed issue with updating discrete element selection.
• Fixed issue with importing partlists from feb4 file.
• Fixed bug in pixel inspector caused by incorrect scaling. Pixel inspector rectangle is now drawn correctly.
• Fixed issue where error string of mesh modifier did not propagate to the user.
• Fixed issue with updating part sections when the mesh is changed.
• Fixed issue where random faces get selected after deleting a face selection.
• Fixed crash when purging selections from model components.
• Fixed bug in render vector plots for element data.
