When you draw an element with more than 5 nodes, the program will mesh your element, whether your assign a meshing or not. When you draw an area element with four nodes only, the program will not automatically "auto mesh" your element (assuming you have not assigning an auto mesh.
Maybe I'm getting something wrong, but wouldn't a cable work first linearly? What's the point in needing non-linear loads to define a element workig exclusively with tension? RE: Area mesh and linear analysis modes on sap2000 v18 If only elastic material behavior is considered, linear analysis methods should suffice." "Nonlinear analysis methods are best applied when either geometric or material nonlinearity is considered during structural modeling and analysis.
However in the CSI knowledge base there's the following But is a mesh different than using a area divide?Īlso I've understood that the only way to get elements working exclusively on tension, like cables, is to put loads on non-linear analysis. So what's meshing about? I believe it creates the linear elements that are used to analyse the model. I've read it's about meshing, but I couldnt quite grasp it, because I defined the 5-sides area with general automesh, and while viewing the analysis model the fem nodes would show up Or I draw a area with more sides and get this When I define polyareas 2 things my happen, either I define a rectangle or triangle and get something like this
I've recently started using sap2000 and I have a few doubts
