Hi,
I got a question about element size and stress. We know that in the area of geometry discontiguous, boundary condition applying and node force applying, there usually gets secondary stress.According to ASME, if we use Sm for primary stress criteria, then we should use 1.5Sm for secondary...
Hi,everyone
I got a question about the using of command 'CYCLIC'. In my model, there are two types of element,SOLID95 and SHELL93. I used CYCLIC to configue the model as a cyclic symmetric one. But after solution, I found a problem that at the share line of the two elment type, the meshing did...
Hi,
A cylinder with internal diameter d=0.09 mm, external diameter D=0.11 mm, and the length L=100mm.One end is fixed,and apply a bending moment 1mm.N on the other one.We can get the maximum deflection equals about 7.56 mm with formula.

Hi,
I am learning contact analysis and I have a problem here. I want to constrain an axis by the friction between it and the sleeve, but the solution went a very time without any error or results. I don't know why.Could any one help me to have a check?
The following is the commands:
/PREP7...
Hi,
I have a question about the classification of primary stress,secondary stress and peak stress in the postprocess after analysis with ANSYS.As we know, in the area displacement constrains applied or geometry discontidiscontinuity, some very large stress would appear, which usually contains...
Hi,
I met a problem,which needs to know the friction factor between steel and concrete. I used 0.4, but someone said it's the maximum value and not saft for calculation.So I wonder the range. Does anyone know it?
Thank you!

Hi,
I met a question.I need to determine the force between concrete and steel plate in it.I seek information about this, but got nothing.
Can anyone give me some advice?

Hi,everyone:
I did a periodic symmetry modal analysis.The structure contains both solid and shell parts.According to the help file,I used 'CYCLIC' command,which make me have to mesh the structure with 'VMESH' and 'AMESH' commands.
I got solid mesh in the solid parts with 'VMESH' using...
Hi,everyone:
I met a problem about CFD. In ANSYS-CFD,the command 'nrotat'is not avalid command. But if I want to simulate a vortex in a tube, which means there is a rotational speed at the inlet. How can I apply the rotational speed and get the vortex in the tube?
Thank you!

Hi,everyone:
I did a modal cyclic symmetry analysis.But in the post1,I can't display nodal diameter.There are just hrm index.
If anyone can tell me how to display nodal diameter in POST1?
Hi,everyone:
I made a model with SOLID95.After solution,I made stress linearize to SX at the same section but with 2 diffrernt 2 nodes path.The section is normal to X aixs.
In my opinion,the membrane stress of the two paths should be equal,but they are not.
I wonder why,and someone...
Hi,everyone:
I made a model with SHELL and SOLID element.After solution,I found peak stress at the connection lines between the two kinds of element.I wonder how to aviod the peak stress.Is there anyone have some ideas about this?
Hi,everyone:
I tried to do a cyclic symmetry modal analysis according to help file.But didn't make it.I don't know where is the problem.Here is my steps:
1) BUILD THE FINITE ELEMENT MODEL, INCLUDING BUILDING GEOMETRY,MESHING,ROTATING THE NODE COORDINATE,AND DEFINE MATERIAL PROPERTIES
2)ISSUE...
Hi,everyone:
In ANSYS,we can just have one path actived.But if I have three paths,which all have an iterm named S1,how can I plot the three 'S1' on one graph? I think command 'GET' maybe do it,but I don;t know how to.

Hi,everyone:
In POST1,we can use command 'RSYS' to modify the result coordinate system,but 'RSYS' is not a known command in POST26. Then which is the result coordinate system in POST26?

Hi,everyone:
I got a question when I calculated the foundation load in a hydralic turbine project.When it comes to the load transported by stayring, should I take the gravity of concrete into account?
Thanks!

Hi,everyone:
After I do a bulking analysis, I got the critical load. But I wonder how can I get the displacement if I apply a load bigger than the critical value?
