[deal.II] error: cannot declare variable ‘postprocessor’ to be of abstract type ‘FracturePhaseFieldProblem<2>::Postprocessor’
Hi,
I built a class called FracturePhaseFieldProblem , which contains a
subclass called class Postprocessor，
template
class FracturePhaseFieldProblem
{
public:
…
private:
…
void output_results () const;
class Postprocessor;
…
};
However when I want to declare a variable as the type
FracturePhaseFieldProblem<2>::Postprocessor in function output_results (),I
got the error:
error: cannot declare variable ‘postprocessor’ to be of abstract type
‘FracturePhaseFieldProblem<2>::Postprocessor’
Thank you very much.
Best,
Yu

[deal.II] Dimension 5440 not equal to 8160
Hi, My code, although there were errors before the change, could run under single core mode. However, after I made some modifications, the following error message appeared. When I run the code before the change again, the following error message will also appear. I just tried to change the error reported in the previous code and added a few parameter definitions. Why do the same code produce different results? Any advice on this issue would be appreciated.

Re: [deal.II] Using KINSOL with distributed vectors
Hi Nori, I'm sorry to bother you again. I would like to know which function you used to obtain vectors without ghost element from vectors with ghost element. If convenient, could you please share the code in this area or your ideas for implementing this process. Thank you very much for your kind help.

[deal.II] An error occurred in line <1467> of file in function dealii::IndexSet dealii::TrilinosWrappers::MPI::Vector::locally_owned_elements() const
Hi al, I am a freshman in dealii. I have installed Dealii 9.4.2 on 22.04. The senior wrote code on the old version of dealii, so I made changes to his code to adapt to the new version of dealii, but I encountered some problems. The function(locally_owned_elements()) where the error code is located has been deleted, but this error still occurs. I want to know where this problem comes from and how I can solve it.
