Dear All,

While solving the Spur Gear (The Dimensions and loads are quoted from a research article), I didn't get the same value as the author got for his analysis. In that paper, the boundary conditions didn't mention clearly. So, by using some engineering assumptions and referring youtube videos I tried to solve that gear, but the error is consistently occurring.

I used full Gear model for analysis, but due to academic element limit, I am unable to solve the full model. I made a 90 deg cut in the gear and used it for analysis. Even though I am getting the error message as shown in figure 1.

To find out the contact stress, I assumed Frictionless contact model for solving the problem. With this discussion, I attached the **details of the RESEARCH ARTICLE, ** **ANSYS FILE, **the picture of **Boundary Condition **and **Error**.

Thanks in advance
