Hi folk
There is an error when running example 21 of dealii-9.2.0, when using
Single curving crack permeability.
this is the error message:
An error occurred in line <457> of file
</Applications/deal.II.app/Contents/Resources/Libraries/include/deal.II/lac/solver_cg.h>
in function
void dealii::SolverCG<dealii::Vector<double> >::solve(const MatrixType
&, VectorType &, const VectorType &, const PreconditionerType &)
[VectorType = dealii::Vector<double>, MatrixType =
Step21::ApproximateSchurComplement, PreconditionerType =
dealii::PreconditionIdentity]
The violated condition was:
false
Additional information:
Iterative method reported convergence failure in step 1024. The residual in
the last step was 2.30266e-12.
this example run very well in previous release of dealii. is this a bug?
Best
F
