Module Description

This module allows the creation and editing of surface and volumetric meshes. Polygonal surfaces in VTK or STL format are imported to begin the process. Then a unique and intuitive bounding surface (called Building Blocks) are created interactively by the user and used to guide automated meshing algorithms. The module includes visualization and analysis reports of the quality of mesh elements. Meshes can be written out in Abaqus of VTK format for later processing.


Usage

Examples, Use Cases & Tutorials

  • IA_FEMesh is particularly well suited for quickly developing quality hexahedral meshes for artificial joint research and prothesis design. Its intuitive interface allows the user to mesh and review moderate sized objects, such as bone surfaces, efficiently. However, the use cases are not restricted to this application area.

Quick Tour of Features and Use

The user interface for IA_FEMesh is organized as a set of tabs, with each tab corresponding to a group of related activities. Often the user will move back and forth between the tabs during the meshing process. The tabs organize related operations yet allow free movement, depending on the users needs. The tabs and associated operations are listed below:

  • Surface: This tab allows input and saving of surface files used to define the object which will be meshed.
  • Building Blocks: After a 3D object surface is input, the user interactively creates, modifies, and views a control surface used to guide meshing algorithms. Under this tab, operations for editing, copying, deleting, and splitting building blocks provide the tools for rapid building block creation.

Development

Dependencies

IA_FEMesh has no external dependcies. It creates meshes in Abaqus format. To perform finite element analysis, the user will have to provide a suitable simulation environment.

As far as the software building process, all required support libraries, that extend the Slicer3 base, are built from source code during the Slicer3 build process automatically.

Known bugs

Follow this link to the Slicer3 bug tracker.


Usability issues

Follow this link to the Slicer3 bug tracker. Please select the usability issue category when browsing or contributing.

Source code & documentation

IA_FEMesh was developed as a standalone program and has been integrated for use in Slicer3 as one of the products of a NA-MIC External Collaboration. A design goal for this effort is to allow software development to continue on both the standalone and integrated module versions while working off a common code base.

Custom GUI classes were created to group meshing operations -- inheriting from a common parent class developed for this module. Doxygen generated documentation of the abstract parent class and the operations as derived classes is available here.
