Hi mates, recently I tried find out what exactly means "iso" what you can came a cross in SolidWorks tutorials and similar explanations but don't mix up with "ISO", please. I guess what that mean but I am very curious what the strict that is. If somebody knows please share your information with another person.
Isoparametric elements describe the parameters of a parent shape class. For instance, all rectangles have certain parameters which describe their construction universally. The isoparametric elements can be used to project the shape onto a coordinate system, and this works in 2d and 3d transformations. http://www.softeng.rl.ac.uk/st/projects/felib4/Docs/html/Intro/intro-node31.html
