I obtained a ChVectorDynamicD with the command : knots = element.GetKnotSquence() but I do not manage to print its content... I tried to get it with : - knots[0] - knots.GetVectData(0) - knots.GetVect() However, each of my tentatives sold with a core dumped. The exact error is : eigen-3.4.0/Eigen/src/Core/DenseCoeffsBase.h:367: Eigen::internal::traits<Derived>::Scalar &Eigen::DenseCoeffsBase<Derived, 1>::operator()(long, long) [with Derived = Eigen::Matrix<double, -1, 1, 0, -1, 1>]: Assertion `row >= 0 && row < rows() && col >= 0 && col < cols()' failed. Aborted (core dumped) Is this the correct way to access the content of a ChVectorDynamicD or is there an other way ?
