Hello everybody,
I'm new to Marc! To train myself I am looking for some useful tutorials on dynamic analysis.
Can somebody help me out here?
thanks in advance,

Hi,
I want to add damping to my model to do a modal analysis. After reading the help files several times and lots of unsuccesful attempt, I need more to the point information.
1. The damping solver doesn't support the constant damping when added to the material model. I want to simulate...
Hi,
by importing an assembly CAD file, Ansys recognizes the different volumes. I need to connect these volumes to perform a modal analysis on it. By doing this, I want to take into account the physical properties of the connection (bolt, guideway,...). Can anybody tell me what's the easiest way...
Hi,
for my internship, I'm verifying the static and dynamic behavior of a milling machine. I was wondering what the influence of stress can be on the dynamic behavior. I'd say that a system under stress has higher natural frequencies. In this way, one could stress up a structure to avoid that...
Hi,
I was wondering: what's the influence of stress on the natural frequencies of a structure. I tried it for my model and I only notice a very small difference in results (0.1 Hz). This seams a bit low in my opinion.
Can anybody help me out here?

Hi again,
I have to find the dynamical behavior of a milling machine. Connexions between the different parts are very important and I want to modelise them as realistic as possible. The structures has a couple of bolt connexions.
I use the contact wizard to define the connexion.
I would like...
Hi,
I was wondering: what is the advantage of using shell elements if the volume can also be meshed with solid elements. Does this affect CPU time?
thanks,

Hello everybody,
I am a first time ansys user, charged with the job to find the natural frequencies and modes of a milling machine. However, I've got a few problems with the results I get.
first problem:
1. I do a modal analysis in the domain 20-200Hz with Power dynamics or Block Lanzcos...
