    Nodal velocity as boundary condition

    Thanks. I have run a few tests but I am confused by getting different results in respect to magnitudes. The model is simple and is made up of a U-beam modeled with shell elements, on top of it at a distance there is a point mass, connected to the beam via rigid elements. The beam is constrained...

    Nodal velocity as boundary condition

    Hello I am interested in an harmonic analysis (frequency response) of a structure made of a mass connected to a frame. The mass can be modeled as a point mass, connected with rigid constrains (or distributed coupling) to the frame, which is modeled by shell elements. I want to apply a velocity...

    Difference between transient analysis and static analysis with time steps

    Yes, I mean dynamic analysis in the time domain (ie not dynamic in the frequency domain). I am just using the language that eg Ansys is using calling such analyses as transient. In my example - the thermal transient analysis gives the temperature distribution as load for the time steps -> the...

    Difference between transient analysis and static analysis with time steps

    Hello I am not so used to working in the time domain, hence this question. What is the difference between doing a transient structural analysis and a static analysis with time steps, where the external load is indeed applied in different time steps? I have seen the following situation. A...

    Relationship between mid shell stresses and top/bottom?

    Hello I have an FE model (linear elastic material, homogeneous) using shell181 elements. The structure is subject to constant acceleration and undergoes a static analysis (antype,static). About shell,mid and keyopt(8), Ansys manual reports: KEYOPT(8) = 2 stores midsurface results in the results...
