The parameter that is used to construct&nbsp; the elliptical disk is a = 5cm, b = 2.5 cm&nbsp; and c = 0.1mm.<\/p>\n<p><\/p>\n<p>The elliptical disk is constructed using Solidwork software and imported to APDL in IGES format. The element type is set as MESH 200 and the type of mesh is set as 4 node tetra since volume mesh is required. However, the mesh is unable to be generated. Initially, the element edge length is set as 0.0001 for the above parameter and the warning is shown as in the figure below.<img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/4679c38b-76b1-4fb0-ac91-ab340055f707\/44e8cd62-b182-4ab3-949b-ab3400724661_image1.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>Therefore, the parameter was changed to c = 0.5 cm (the thickness is increased).
