Thanks for your help! I need to avoid surface contact, so the two bodies function as one part and one mesh. Sorry if the follow questions seem mundane, but I'm having a hell of a time finding good Workbench tutorials. 1. When I open a new project, double-click "structural analysis", what...

I'm just learning how to use Ansys Workbench 13 to analyze static structures. I need to analyze the deformation of a simply supported beam with a concentrated force in the center vertically downward. I have a 3D model of this beam created in Solidworks. How do I create a force in the center...

Anyone want to qualify my answer here? Should I re-post this somewhere else? Hello?

I may have found my own mistake. I totally forgot to take into account to volume of the tank. I believe this wound change the Flow Out equation to: C_{out}=(1-x)FC(t) so the final equation would be: \frac{dC}{dt}=xFC(t)-\frac{(1-x)FC(t)}{V} is this...

Homework Statement A rigid tank of volume "V" contains salt dissolved in water at a concentration "C". Fresh water flows into the tank at a rate of "F". A fraction "x" of the exit flow is recirculated back into the entrance flow. Given: V, Volume of tank Fin, Flow rate in Fo, Flow rate...

Excellent, that's just what I wanted to hear! I don't think I know enough about differential equations or Mathematica to understand Matthieu's Differential Equation or the Bessel Functions (is that he name of the functions that are the solutions?) yet, but I can definitely get Mathematica to...

Oh! Okay! I see what's going on here much better now. You're right, it is a ton of arithmetic. I don't understand why anyone would do this by hand when Mathematica exists, but clearly my instructor wants us to. Now, will this method work for any non-poly DE in the same form? Such as y'' +...

Okay, I think I'm making some headway. if I'm understanding this correctly, the book is calculating c_{1}, c_{2},c_{3},c_{4},c_{5} first with the assumption that c_{0} = 1 ; c_{1} = 0 then with the assumption that c_{0} = 0 ; c_{1} = 1. The 1 is coming from the fact that the book is assigning...

I read over the the Wolfram page on Matthieu Differential Equation and it's all pretty much Greek to me. This is an example problem in my book on how to solve a non-polynomial DE, but if I can't figure out how to work the example I certainly can't work the other problems. I understand why the...

Seems I'm just stupid and didn't realize you just multiple the power series of cos(x) and y together to form a new series... So, on to my next question. How does the book "arrive at the general solution y = c_{0}y_{1}(x) + c_{1}y_{2}(x) " ? And how does it determine y_{1} and y_{2} from that?

I need help solving the rest of an example problem in my book, please. Homework Statement Solve y'' + (cos[x])y = 0 Homework Equations y = \sum_{n=0}^\infty c_{n} x^{n} y' = \sum_{n=1}^\infty c_{n-1}x^{n-1} y'' = \sum_{n=0}^\infty n(n-1)c_{n} x^{n-2} The Attempt at a Solution y'' +...
