Would it be possible to solve the below ODE with one specified BC and one constraint in the FlexPDE? if possibe, could you give soem directions?
Governing Equations
--------------------
nu: 2*(1+nu+nu^2)*nu'*nu'' + (2*nu+1)*(nu')^3 = 0
Boundary Condition
-------------------
nu(-1) = 0,
Constraint
-------------
N=integral( nu*dY ) dY from Y=-1 to Y=1
N is given a constant |

The equation is second order, so two integration constants are required. Theoretically, one BC and one constraint could supply these values. Why not try it and see what happens? |
