Rasberry pi
Raspberry Pi hybrid mesh


Raspberry pi with case surface mesh made of triangles and quadrilaterals, the main volume mesh consists of tetrahedrons with prisms in the boundary layer formed using the T-Rex method. The T-Rex max number of layers was 30 in the inflation region with a growth rate of 1.2 between successive layers. The solid components have been meshed with either hexahedra or prisms. The exported mesh has been tested with OpenFOAM-v2006 simpleFoam, and converges well, however only tested at a lower speed. The provided mesh was exported from the Pointwise case file included with the download. If you want to modify or re-export the mesh, you will need a licenced version of Pointwise.

Use the freely available Pointwise Viewer to view virtually any mesh file in 3-D, display it in a variety of styles, and compute any of dozens of mesh quality metrics. Built-in mesh importers are available for two dozen formats, including CGNS, FUN3D, OpenFOAM, SU2, UGRID, and more. If your mesh format isn’t available, an SDK is available for you to write your own mesh importer that appears in the GUI automatically at startup. The meshes can be displayed however best suits your needs: wireframe, hidden line, solid fill, or shaded. Tools are available for measuring distances. And you can assess your mesh’s quality by computing and displaying a wide variety of metrics, including Jacobian, skewness, size ratios, and more. Pointwise Viewer also provides geometry model viewing capability for models in ACIS, CATIA, Creo, IGES, STEP, SolidWorks, STL, and other formats.
