Hello! I started recently to use ANSYS Workbench 15 to solve a stiffness problem of a three parts assembly. I have a general knowledge about FEM. I create the geometry in the Design Modeler by inserting the assembly from Solidworks 2010. It is a three parts assembly like a bicycle's wheel. Two...

Hi everyone, I have recently installed ANSYS 14.5. But after opening workbench, while trying to open Fluent I am getting problems like "Unable to start the geometry editor." and "Unable to start the Meshing editor." I have attached the error screen shot. Please help me out in this. Thanks a lot.

Hi, I'm analyzing a composite leaf spring using ANSYS APDL, the leaf spring has a thickness of 12mm, and since it is a composite material, it is composed of many plies, I'm assuming the ply thickness to be 0.125mm. I imported the geometry as a Parasolid x_t. And the element type I used is...

Hello, I am trying to make contact between a stationary line body and a moving plate that will compress the line body. But I could not make contact between them. There is also a automatic connection generated but while simulation it does not show the contact instead the moving plate...

how change the standard adopted during designing in ANSYS Static Structural? i am new in ANSYS. Please help

Hi friends, I am working on a model of linear generator. I have modeled the linear generator in Ansys 2D. Now I want to attach a spring to one end of the rotor and see how it works with the spring attached to it. How do I model the spring? Also is there any proper way to determine the damping...

Hello I am new to Ansys and currently conducting a study on ''property of lightweight structures'' I have read and watched videos online but nobody has the tutorials...i'm hoping someone here can help me on how to model a multi-storey building using Ansys...I hope this post makes sense. Thanks

Hi, We have an axial fan in the lab that apparently vibrates badly ("wobbles") at certain frequencies. To find the resonance and the bad frequencies, I decided to do an ANSYS modal analysis. I am still pretty new to it, and have a few questions. 1) Regardless of how many modes I pick...

I'm an intern currently and doing some analytic project in a company. So i am required to determine the gap between 2 contact surface (2 O-rings). I've obtain some result by using "node to node" contact with some commands and also probe "gap". There's some difference between the results and the...

I have to model a storage vessel in ansys and perform stress analysis for it. I have no idea about which element types I will need for the analysis. I have calculated the design dimensions for the vessel. I am a beginner at ansys and know only how to deal with simple structural and thermal...

This is more complicated than it sounds. I'd like to analyse a fracture in a surface body so I need to create a no thickness or infinitesimally small cut/slice if it is possible. Afterwards, I'm planing to analyse stress concentration factor in model environment.

My tutor only knows how to do it with APDL and I seek for a more up to date Workbench solution. How do I evaluate stress concentration factor for a surface plate with a fracture going straight through it (like a slit - no crack width, only length)?

Hi all, I am trying to open my model from v.16 into v.15 with no success. I have dragged a mesh/Finite element modeler from my original model and Write solver model in an Ansys Mechanical APDL file and got to save my model as an inp. When reopening a FEM in ansys 15 and importing this (Inp...

Hi all I have few questions in bldc motor simulation in maxwell 2d: - I need help in loss calculation,I exported a bldc motor in rmxprt to maxwell 2d after entering core properties and w/kg data in 50hz,in 2d checked stator and rotor in set core loss and checked (consider core loss effect on...

Why is the Lorentz force calculated in Ansys so low? According to the formula F=B*I*l, it is supposed to be at least 1000 times higher. The model is really simple: a magnetically conductive plate in a static magnetic field inducts the magnetic field from the surrounding space, which makes its...

Hello all, I am a new user to Ansys. I am currently using it for fracture mechanics analysis to calculate the stress intensity factor(SIF). I am supposed to calculate the SIF for different force applied to my model. The forces are on an excel sheet. Is there some way I could link this excel...

Hi! I am new to ANSYS and I am trying to understand a simulation done by some one else. I have a disk with a spiral in it, and it looks like there is a remote force being applied at the centre of the disk, but spread over the entire face. I don't understand how this force is being spread...

Hi, I am trying to simulate a moving load in ansys 15. Could anybody guide me on how I could do it? A typical example: Calculating stress across a steel Rope ( assume solid circular c/s) between point A to B while a pulley load moves over it between the 2 points with a certain velocity. I will...

Hello experts, Is it possible to run several instances of Ansys Mechanical in Windows or Linux in parallel? How? I need to dramatically speed up the solution of a large list of Ansys Mechanical jobs, typically more than 50000. Such analyses are performed by some script that runs each job in...

Dear experts, I´m trying to model in ANSYS Mechanical (v14.5) the linear buckling behavior of a cylinder made of BEAM4 elements under combined loading (axial compression and bending moment) applied at the ends. How should I set up the boundary conditions of a cylinder to keep rigid the ends...

ANSYS can be used to model creep in a number of different ways. If you are designing to ASME Section VIII, Div., 2 you might have to verify that your design meets the "shake down to elastic action" criteria. Basically, that means that the strains do not continue to increase over the number of...

All, I recently completed a project where transient thermal boundary conditions are rotated around a cylinder for a general number of revolutions. In reality, the cylinder rotated but it was much easier to rotate the thermal conditions around the model in the ANSYS environment. I used 360...
