Eval()

virtual real_t mfem::TMOP_LimiterFunction::Eval ( const Vector &  x, const Vector &  x0, real_t  d  ) const

pure virtual

Returns the limiting function, f(x, x0, d).

Implemented in mfem::TMOP_QuadraticLimiter, and mfem::TMOP_ExponentialLimiter.

Eval_d1()

virtual void mfem::TMOP_LimiterFunction::Eval_d1 ( const Vector &  x, const Vector &  x0, real_t  dist, Vector &  d1  ) const

pure virtual

Returns the gradient of the limiting function f(x, x0, d) with respect to x.

Implemented in mfem::TMOP_QuadraticLimiter, and mfem::TMOP_ExponentialLimiter.

Eval_d2()

virtual void mfem::TMOP_LimiterFunction::Eval_d2 ( const Vector &  x, const Vector &  x0, real_t  dist, DenseMatrix &  d2  ) const

pure virtual

Returns the Hessian of the limiting function f(x, x0, d) with respect to x.

Implemented in mfem::TMOP_QuadraticLimiter, and mfem::TMOP_ExponentialLimiter.
