I've been asked by the head engineer of the company to lay out a design for a superelevated, reverse curve with no tangent section between curves. I think it's impossible, as the superelevated curve must remain superelevated throughout the entire curve, right? For the speed to remain constant...

Hi everybody, Does anyone know how to perform a frequency analysis of an infinite pool of water using fluid elements as programmed in ADINA ? Any input is very appreciated.

Does anayone know when SAP uses non conformiung elements for stress analysis. I used ASOLID option and the results I obtain surely don't use non conforming elements, so there should be another way to specify that. I know this is possible with the SOLID elements options, but I prefer a 2D...

Yes I agree with you, but what I don't understand is why 2 other commercial FE packages (SAP and ADINA) don't consider this step in the analysis.

Hi all, I am reading a finite element program listing code (plane stress or strain analysis of solids), and I find a section where the programmer is talking about the 'elimintation of auxiliary degrees of freedom' when implementing the elementary matrices. Can anyone tell what this step is for ...
