Marc Amsler Marc Amsler Marc Amsler (born February 5, 1891 in Vevey, Switzerland – died May 3, 1968) was a professor of ophthalmology in the Eye Clinic at the University of Zurich. He took the position as professor of ophthalmology in Zurich in 1944. His predecessor was Prof. Alfred Vogt. Prior to assuming the position at Zurich, Dr. Amsler was chief ophthalmologist in Lausanne, since 1935. His predecessor there, under whom he worked beforehand, was Jules Gonin. During his time in Lausanne, Amsler was instrumental in creating the Jules Gonin Medal which is awarded every four years and is considered the highest
Unstructured grid to triangles and tetrahedra, other commonly used elements in finite element simulation include quadrilateral (4-noded) and hexahedral (8-noded) elements in 2D and 3D, respectively. One of the most commonly used algorithms to generate unstructured quadrilateral grid is "Paving". However, there is no such commonly used algorithm for generating unstructured hexahedral grid on a general 3D solid model. "Plastering" is a 3D version of Paving, but it has difficulty in forming hexahedral elements at the interior of a solid. Unstructured grid An unstructured (or irregular) grid is a tessellation of a part of the Euclidean plane or Euclidean space by simple
