Hi,
I am trying to simulate a face milling operation in ansys, comprising of a 1000 mm job and a 125 mm diameter cutter. I have defined a displacement path for the job under analysis settings but when I start solving, the application stops responding or takes a very long time to solve. Can anyone check what might be the problem? PLEASE HELP. I wanted to enclose the geometry and mesh files in .zip format but they are too large. If anyone is interested, please provide an email id. However I am attaching some images, but still can't attach more than five of them. Capture1.jpg Capture7.jpg Capture8.jpg Capture9.jpg Capture2.jpg |

In the contact tree you have both frictional contact and body interaction defined. I think body interaction is enough (it detects touching surfaces automatically between all parts or the parts you have defined).
In my opinion you have way too much elements in the model. Also you can reduce nodes/degrees of freedoms by using hexahedral meshing. |
