Modeling with ANSYS – Geometry and Element type• The geometry and the element type have to be considered together.• Shell element are typically used for structure where the thickness is negligiblecompared to its length and width• Nevertheless, a plate modeled with solid element would provide similar results. Thedisadvantage lies in the computation time.• Ansys provides a large choices of elements.Shell181 Shell281 Solid186www.structures.ethz.chCENTRE OF STRUCTURE TECHNOLOGIESFull Name01.03.2011, page 6
Modeling with ANSYS – Geometry and Element type• The Ansys command to define the element type is:• The geometry is defined with key points that are connect together to obtain either anarea or a volume.4:(0,0.5,0)1:(0,0,0)3:(1,0.5,0)2:(1,0,0)www.structures.ethz.chCENTRE OF STRUCTURE TECHNOLOGIESFull Name01.03.2011, page 7
