DESCRIPTION:Title: <a href="https://researchseminars.org/talk/cam/27/">Mat
 erial distribution topology optimization for boundary-effect-dominated pro
 blems</a>\nby Eddie Wadbro (Karlstad University) as part of CAM seminar\n\
 nLecture held in MV:L14.\n\nAbstract\nIn the classical design optimization
  using the material distribution method (density-based topology optimizati
 on)\, a material indicator function represents the presence or absence of 
 material within the domain. The first part of this talk provides an introd
 uction to material distribution topology optimization with an emphasis on 
 mathematical morphology\, non-linear filters\, and length scale control.\n
 \nTo use the material distribution approach for boundary-effect-dominated 
 problems\, we need to identify the boundary of the design at each iteratio
 n\; this talk discusses two methods to achieve this. The first is to use a
  boundary strip indicator function defined on the elements of the computat
 ional mesh. The second is to use a boundary indicator function defined on 
 the mesh faces (edges in 2D and facets in 3D). The second part of my prese
 ntation covers the main ideas behind both approaches and showcases results
  from two applications\, one suitable for each approach.\n
