Topic: Finite element types in ATENA 2D
I am simulating an interface failure model using ATENA 2D for which I use quadrilateral elements and interface elements for my model. Is there a way to know whether the finite elements that I am using are linear or quadratic?
Codes for the respective elements are CCIsoQuad and CCIsoGap but no specific distinction between finite element type is given. Is this information provided in the manual somewhere? I checked the manual for GiD as well, in that number of nodes is specified in the code for example, IsoQuad<xxxx> for linear elements, IsoQuad<xxxxxxxx> for quadratic elements. However, I cannot find a clear distinction like this while using ATENA 2D.
Kindly guide me in this matter.
