[petsc-users] TSAdjoint not working correctly when using TSThetaSetEndpoint(true)

[Salazar De Troya, Miguel]

Hello,

I am attaching a simple example that uses TSAdjoint to calculate the sensitivity of a 1 degree of freedom ODE. When using theta methods, it returns the right sensitivity as given by the analytical solution. When I set `ts.setThetaEndpoint(True)`, it does not work. Is there a theoretical reason why? I was using this option because using the options

ts.setType(ts.Type.THETA)
ts.setTheta(0.5)
ts.setThetaEndpoint(True)

is equivalent to using ts.Type.CN

Thanks
Miguel
