    <div class="sphx-glr-thumbcontainer" tooltip="Mesh coarsening can be performed as part of a mesh quality improvement process, or to reduce the resolution/complexity of a mesh for various other purposes. The Contract function supports coarsening of either tetrahedral or triangular meshes by contracting edges to achieve the desired edge length. For non-triangular or non-tetrahedral meshes, they can be first  converted using solid2tets or surf2tris (see also Conversion).">

    <div class="sphx-glr-thumbcontainer" tooltip="This example illustrates the effects of different smoothing methods. Smoothing a mesh can serve two purposes - the first is to smooth the geometry, rounding out sharp features; the second is to redistribute nodes, often in pursuit of improved element quality. When attempting to improve element quality, often the goal is to redistribute the nodes while having a minimal effect on the geometry. Different smoothing methods have different effects on the geometry.">
