Are there direction-dependent Constraints realisable in APDL (ANSYS 14.5)?

I want a line to be able to move in only negative x-Direction. If the line ever gets (back) to x=0 it should be constrained.

Is Anisotropy caused by using a Hardening-Model in ANSYS (Implicit)?

In a non-linear, implicit Process (2D), I start with anisotropic Settings and three E-Moduli for the three Directions of Freedom. When I use a hardening Model in ANSYS (Kinematic Hardening or...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

What test should I use to compare two or three means, if data is not normally distributed but sample size is > 30 in each group?

I personally feel this as a most confusing question. As per my understanding, if sample size is > 30, and sample is skewed, we can still use paramteric approach, as it will follow Z...
