...all you need to do is apply a pressure function with the following
P0e1i.k.x such that x is the distance where your pressure will be applied and k=2*pi*frequency/c all are constants except for frequency
This is similar to the way ANSYS simulates harmonic analysis with rotating forces or ocean...
I might have an idea although I do not know how to implement it, "don't know much APDL" you can add a command snippet...I will explain my idea in

since I need to have periodicity as well
I hope it helps
How to simulate elastic wave propagation in Solids?
a) How to model an incident P-wave (Pressure Primary longitudinal wave) or SV, SH-wave
The incident wave will be harmonic and it has periodicity in the direction of propagation
P-wave is P=P0e1i.K.xe1i.omega.t
S-wave is...

@ rbpmc I just tried today the idea of sketching on surface then writing text. I picked wingdings font then pick the arrow the arrow did not align with the edges. I do not know why. I can place the arrow on either side of an edge ...
Thanks to anyone who suggested anything for your suggestion
@rbpmc I did not fully understand your suggestion. I do not have solidworks right now. I have it on a different computer but let me tell you what I am thinking of doing:
-Use surfaces to create planes (thickness will not be an issue)...
@CorBlimeyLimey
I used the standard planes and was able to change their transparency. However, I could not change each plane color. I was able to display them intersecting each other but could not make them intersect bodies. I thought about creating parts to represent planes but did not like it...
I am trying to create simple illustrative figures, like the ones you see in textbooks. My figures are a bit different I have a cylinder in space that is cut by three perpendicular planes (standard planes) and an oblique plane. The a vector perpendicular to the oblique plane surface makes two...
I am using ANSYS full in Harmonic response analysis. My model is made up of one part which is made up of more than one body. (A composite fiber of 3 layers).
Whenever I add frequency response at a point between layers, it would not work. I get an error message that the point is on different...
...vibration you can use Harmonic response analysis. Yes harmonic response solves for a range of frequencies. If you desire a specific frequency
F=F0*sin(omega*t). Then, see the results for that particular frequency. The harmonic response provides results for a range of frequencies.
Now to my...
Thanks hacksaw,
I did not understand
Let us say you wish to model
m (dx/dt2)+ c (dx/dt)+ k x = F
and F is F=F0*sin(omega*t)
what type of analysis would you use?
if I may add to Harmonic response analysis. Not only it is a range of frequencies but also it does not apply the harmonic frequency to the force.
What would be the best way to study harmonic forced vibration?
Hi All,
I am not sure how to use FE software and specifically ANSYS to conduct Forced vibration analysis.
ANSYS has the following types of Analysis:
Modal Analysis (basically calculates natural frequencies and mode shapes)
Harmonic Analysis (provides the harmonic response under a range of...
An update still not quiet sure
-the x (radial), y (axial) and z (tangential) directions
I thought
-the x (radial), y (tangential) and z (axial) directions
That is at least how they were displayed on the screen while creating the coordinate besides I picked the orientation to be around z axis
Can anyone guide me on how to find specific help? Is there a specialist that I can talk to about specific problems like this?
It is unfortunate that no body uses command snippet where I am. It is also unfortunate that it is hard to find those who worked in the same area.
