Is Simpson's Rule Effective for Solving the Intersecting Cylinders Problem?

[Xishan]

Best numerical technique?

I've recently used Simpson's (1/3) rule for the numerical solution of the 'intersecting cylinders' problem. I've found that it isn't too accurate no matter how many intervals I take (I have even taken 1000,000 intervals!), but still end up with some error.

I'll appreciate anyone for helping me in this matter

What is the intersecting cylinders problem?

 

[Xishan]

it is discussed in the thread called 'intersecting cylinders' in this forum. the results of numerical integration do converge but always with some error
