Ansys Definition and 377 Threads

Hi, I am trying to use ANSYS workbench to model a steel frame with steel cross bracing (HSS 32*32*3). The post-buckling behaviour should be similar to the Remennikov-Walpole analytical model (1997) where in a rigidly fixed ended brace three plastic hinges will form in buckling. The expected...

Hi all. I don't have as much experience with thermal analyses in ANSYS, and I can't quite figure out a problem that I'm working on. I'm trying to find the temperature distribution in a box that has a circle in the center. I want to define constant temperature b.c.'s at the walls and the circle...

If I am using a new material in ansys, let's say I assigned it as solid linear elastic and I assigned density, young's modulus and poisson's ration and then I applied large deformation for this material so that it should be experience non-linearity ...I wonder how Ansys can give the results...

I am doing a 2D Ansys workbench simulation ,it is nonlinear simulation due to frictionless contact, there is symmetry in the shape so I used the symmetry option to reduce the computation time and it succeeded to converge after that I tried the simulation of the whole body but it always fails...

Hi everyone,, I am modeling the debonding between concrete and CFRP subjected to tangential loading (Mode II) using ANSYS Workbench, I used (CZM/VCCT) techniques to model the debonding. as you know with workbench you can't choose the element type directly. you have to insert commands for...

What happens if I turned off large deflection in a simulation which has large deflection in Ansys workbench ? should the solution be totally wrong ? will it fail to solve ?

As far as I know both the friction or the frictionless contact types in Ansys doesn't prevent motion in the perpendicular direction. I have been following this tutorial https://goo.gl/w8sIlG (no need to open) but I have found something strange when I do the same but without changing the analysis...
