  2. Project Description • What is the CMB? • Cross-platform framework of tools for pre- and post-processing of numerical simulations

  3. Large, Complex Domains • Minimize 2D/3D mesh manipulation on desktop • Set up problems on geometry • Tag surfaces of shells (3D) or edges (2D) for boundary conditions • Separate geometric model from computational model • Postpone building the computational mesh until the very end

  4. Client/Server http://www.bestbuy.com/site/ http://www.erdc.hpc.mil/systemNews/Cray_XT4/home HPC • Run as client-only or client-server • Save model files on HPC or on client • Build meshes on HPC or on client • Visualize HPC results without moving data

  5. Cross-Platform • Researches running on multiple platforms • Mac OSX, Windows, Linux • Built on top of OpenGL, QT, VTK, and ParaView • Plugin framework

  6. Scene Builder Points Builder Model Builder Sim Builder Mesh Viewer Meshing and Simulation Model Builder 6

  7. Sim Builder GUI is dynamically built from XML template

  8. User Configurable

  9. Large Scatter Datasets

  10. Cross-Sections

  11. Generating Arcs

  12. Splitting Arcs and Creating BC Sets Left: Spliting an arc Right: Creating an edge boundary condition set

  13. Post-Processing

  14. Post-Processing

  15. Future Work • Need 2D/3D mesh generators • Mesh refinement • CAD support • Geology modeling
