Hi Foamers,

I encountered a problem when run a tutorial using my simply modified solver.

I try to simulate a prescribed motion using sixDoFRigidBodyMotion solver. So I modified the symplectic.C in src/sixDoFRigidBodyMotion/sixDoFSolvers/symplectic/.

The only thing I changed is the calculation of centreOfRotation.
The original formula is: centreOfRotation() = centreOfRotation0() + deltaT*v();
In my modified file it is:
centreOfRotation()[0] = centreOfRotation0()[0] + deltaT*v()[0];
centreOfRotation()[1] = centreOfRotation0()[1] + 0.2*sin(6.28*t);
centreOfRotation()[2] = centreOfRotation0()[2] + deltaT*v()[2];

I want to make the body conduct a heave motion in vertical direction with sinusoidal function depend on time. Anyway, the solver is compiled well.
Then, I test the modified solver using wingMotion tutorial, but got the following error:

Hope anyone who has relevant experience can provide me some suggestions. Any information is appreciated.
