has_stable_inverse()

bool serif::utils::checks::has_stable_inverse ( const ::mfem::DenseMatrix & matrix )

inlinenodiscard

Check a one- to three-dimensional square Jacobian before asking MFEM to invert it.

Note

Use MFEM's scale-relative singularity criterion in all build modes, so invalid geometry can be reported as a value instead of triggering its debug assertion. Uniform coordinate scaling is permitted.

is_finite() [1/3]

bool serif::utils::checks::is_finite ( const mfem::DenseMatrix & matrix )

inline

Check all entries of a small MFEM dense matrix.

is_finite() [2/3]

bool serif::utils::checks::is_finite ( const mfem::Vector & vector )

inline

Check every MFEM coefficient before publishing a numerical result.
