# Gallery

This page collects screenshots from various simulations that have used GLVis visualization. Additional images can be found in the MFEM Gallery.

*The GLVis logo is derived from the Metatron model at bathsheba.com. Shown is the magnitude of the projection of a smooth vector field using 4th order Nedelec elements on a second order curved tetrahedral mesh (based on MFEM's Example 3).*

*Axisymmetric problem with revolved 2D mesh and solution, plus coloring grid functions emphasizing mesh elements. See also the video.*

*Unstructured parallel decomposition of a fourth order NURBS mesh of the unit ball obtained in the solution of MFEM's parallel Example 1 on 16 processors.*

*One of the eight order (Q8) basis functions on the reference square. The sub-refinement in GLVis (key 'i') allows for the correct visualization of such high-order functions.*

*GLVis model opened in augmented reality with the glTF model viewer.*

*Curvilinear 8th order mesh from a triple-point shock simulation in the MFEM-based BLAST shock hydrodynamics code. Click for a movie of the evolution of the processor partitioning from a high-resolution parallel run of the problem produced with a GLVis script.*

*Raytraced glTF model in Blender which was exported from GLVis with the 'G' key. The mesh faces have been cut with 'Ctrl+F3'*

*3D Arbitrary Lagrangian-Eulerian (ALE) simulation of a shock-triple point interaction with Q2-Q1 elements in the MFEM-based BLAST shock hydrodynamics code. Shown are the cutting plane and level surface capabilities of GLVis.*

*Parallel partitioning of a non-conforming adaptively refined mesh between 2048 processors based on splitting a space-filling (Hilbert) curve.*

*Level lines in 2D. Simulation with MFEM.*

*The SIAM CSE13 logo illustrates the decomposition of a hexahedral zone in tetrahedral "sides". This and related images can be found in this paper.*

*The vector field solution of grad-div problem on a periodic mesh computed with hybridized 3rd order Raviart-Thomas elements. Lines correspond to backward Cartesian displacements (key 'd' in GLVis).*

*Stitched parallel results from hypre's Example 4 on 36 processors.*

*The solution of the Laplace problem on a 3D NURBS mesh. Shown are the solution values in a cutting plane and one of the internal boundaries.*

*Locally refined grid in 2D. Simulation with MFEM.*
