Getting NaN when using the analytical solution

Hi there,

I am using RLine v1.2 to simulate a network of roads, and if I try running RLine with the analytical option, I get NaN and Infinity values in the output. I don’t get that when using the numerical solution, but I would like to use the analytical solution to speed up the process. Are those NaN or Infinity results unavoidable in some situations when using the analytical solution?
