ansys 13 basic doubts

[tele]

Good morning to all,
I am novice both of the forum and of the product ansys that I am beginning to use for a thesis work.

doubt 1
from what I have understood until now ansys allows two ways of modeling:
a)definition nodes and elements (example beam and links)
b)definition of areas and volumes and subdivision in mesh according to the element attributed (plane, solid, shell)
in the case of a beam element to 2 knots, I must specify the cross-section, but then also coming at the bottom of the calculation I always get only monodimensional views (it always holds a line). possible does not exist a way to see it in 3d? or should I model it as volume and treat it as a solid element?

doubt 2
if you want to model two solid elements with a bond between them (no matter which) in the hypothesis that it has two solid elements to 8 knots how to proceed?

doubt 3
until I stay in the plan I have no reference sys issues.
when I plan to create a simple spatial travail with beam elements, at the time of introducing the loads does not recognize the direction of these, although it always inserts the same face of application and same value (e.g. negative).

I hope someone more experienced can enlighten me. . .
thanks to all and good day

doubt 1you can also view items in 3d. from the menu at the top do
placontrols -> style -> size and shape
and in the window opening next to "display of element" select "on".
Alternatively type on the command line /eshape,on and then /replotdoubt 2There are many ways, for example with the "constraint equations".doubt 3only pressures refer to faces. you have to properly move the "work plane" and align the coordinate system with the "work plane".
tipsIn the ansys guide there are tutorials, I suggest you do them.
other tutorials find them qui

Thank you very much for the advice.
the tutorials provided by the help I made them (the ones that concern my field of application, i.e. structural and modal), however they refer to specific cases and seeing how much you are ferrata, you will surely know that they are not enough to learn all the settings necessary to a generic case.

I strongly hope to benefit from the tutorials you suggested.

while I ask you one more question:
I have to model a simple beam (using beam elements at 2 knots) with two supports to the extremes and a negative pressure on the upper face, I realize that if there are no intermediate knots I do not get any information about the behavior of the element between the two bound nodes (deformation, efforts excluded the case of axial effort...). vice versa if I insert intermediate knots the game succeeds. depends on the fact that in beam element keyopts is set as linear (and not as squarec) or is it a question of discretization of the element (which in the case of a single element to 2 knots is nonexistent)?

Thank you for your availability,
Good day

Shouldn't I use workbench instead? It seems more intuitive. . .

Can you explain the difference between the two?

(x the beam in 3d works thanks a thousand)

 

[stefano.garbin]

with only one element, more linear, it is mathematically impossible to see the bending in your case.
draw a line, make us over a mesh with a dozen elements, set the constraints at the ends and you will see something more sensible.

ps: workbench is much more intuitive, but for beams in my opinion you should continue using the classic ansys.

hello to all,I am struggling with a conical panel reinforced by 10 double t stringers and finished the optimization I got a certain structure of a weight of about 10 tons.I would need to know the weight to the unit of area so that I can compare this solution with other 30 and 50 stringers.any could help me?thanks in advance
