Finite element meshes of graphite foam samples for Image-Based Simulation (IBSim) of experimental laser flash analysis
<p>Image-Based Simulation (IBSim) meshes:<br> Finite element mesh of laser flash analysis (LFA) disc samples made of a graphite foam material (KFoam). The IBSim meshes are generated directly from a 3D volumetric image of a graphite foam block. The 3D image was generated with an X-ray tomography scan performed by Dr Llion Evans with Manchester X-ray Imaging Facility equipment, which was funded in part by the EPSRC (grants EP/F007906/1, EP/F001452/1 and EP/I02249X/1). Segmentation of the data into a binarized image was achieved with ImageJ. Conversion of the segmented data to FE mesh was achieved using ScanIP, part of the Simpleware suite of programmes, version 7 (Synopsys Inc., Mountain View, CA, USA).</p> <p>The graphite foam has anisotropic properties partly due to its microstructure. This dataset contains three meshes, one for each alignment along cartesian axes.</p> <p>The FE meshes use the EnSight Gold file format and may be visualised using Paraview (<a href="https://www.paraview.org">https://www.paraview.org</a>).</p> <p>The CT data used for the mesh is available as a separate dataset:</p> <p>This data was used originally for the following publications (please cite if re-using the data):<br> Ll.M.

Finite element analysis results from simulation of fusion energy heat exchange component: hybrid CAD/IBSim model including a graphite foam interlayer
<p>Temperature profile data from a finite element analysis of a conceptual design for a fusion energy heat exchange component (monoblock). The mesh is a hybrid from a computer aided design (CAD) drawing for the pipe and armour and IBSim for the interlayer. The IBSim interlayer is generated directly from a 3D volumetric image of a graphite foam block (KFoam). The 3D image was generated with an X-ray tomography scan performed by Dr Llion Evans with Manchester X-ray Imaging Facility equipment, which was funded in part by the EPSRC (grants EP/F007906/1, EP/F001452/1 and EP/I02249X/1).

Finite Element Simulations of 2D Bravais lattice family within photonic crystals fabricated on a photopolymer material via three-beam holography
<p>Videos illustrating Finite Element Simulations of 2D Bravais lattice families within photonic crystals fabricated on a photopolymer material through three-beam holography. The two-way diffusion model is used to simulate the photopolymerization process during the recording process and the formation of the diffraction grating. The simulation results are under a CC license. <br><br>Maged Shaban</p>
Finite element meshes of conceptual designs for a fusion energy heat exchange component (monoblock) for Image-Based Simulation (IBSim) of in-service conditions
<p>Image-Based Simulation (IBSim) mesh and temperature analysis results:<br> Finite element meshes of conceptual designs for a fusion energy heat exchange component (monoblock).</p> <p>The dataset includes three meshes:<br> - CCFE_ThBr_CAD (mesh created by with a computer aided design (CAD) package)<br> - CCFE_ThBr_IBFEM (hybrid CAD and IBSim mesh, manufactured version of CCFE_ThBr_CAD)<br> - IPP_WfCu_IBFEM_3MB (hybrid CAD and IBSim mesh, tungsten fibre-copper matrix composite pipe with tungsten armour)</p> <p>For the the hybrid meshes, the IBSim part is generated directly from a 3D volumetric images of the real manufactured parts and as such includes microscale features introduced during the manufacturing stage. The 3D images were generated with X-ray and neutron tomography, the datasets are available at the links below.
