    Ellipse Through Points?

    Thanks a lot everyone for you responses. I posted here because I thought there was a trick in AutoCAD that I was missing. Apparently not.

Here is what the drawing looks like. I have used a spline and fudged the ellipse in the top drawing...

    ODE Solver Integration Tolerance

    Hi, I am trying to solve a coupled system of 2nd ODEs for a few different values for the constants in the equations. Most of the values give me the following error: Warning: Failure at t=1.098161e-001. Unable to meet integration tolerances without reducing the step size below the...

    How did you get started

    Thanks to everyone for their input. Randal Heller wrote "The job market is not that bad right now". Perhaps it is better where you live. In Canada, the big companies like Bombardier are laying off people. Master's I have applied but the competition is really tough. More people are...

    How did you get started

    Hi I am trying to start my career as an aerospace engineer. Since this site is full of people who have successfully done that, I thought someone could tell me how they got started.
