In this way a 3D mesh, composed of 15-noded wedge elements is
formed. Where needed extra element levels are automatically introduced, so that the size of the elements in y-direction is about equal to the average element size defined for the 2D mesh. If multiple boreholes are used and not all layers are present in all boreholes,so-called degenerated elements will be introduced, to deal with the transition between the various layers.
请教Where needed extra element levels are automatically introduced, so that the size of the elements in y-direction is about equal to the average element size defined for the 2D mesh.怎么理解？谢谢回复，在此表示感谢~~~
