Mohammad,
in addition to what Timo already said, I think it's worth making the
point again that is already an FAQ:
http://dealii.sourceforge.net/index.php/Deal.II_Questions_and_Answers#deal.II_aborts_my_program_with_an_error_message
Namely: Read the error message. For example:
--------------------------------------------------------
An error occurred in line <2246> of file
</home/smm/Work/deal.II/include/deal.II/lac/sparse_matrix.h> in function
void dealii::SparseMatrix<number>::add(unsigned int, unsigned int,
number) [with number = double]
The violated condition was:
numbers::is_finite(value)
The name and call sequence of the exception was:
ExcNumberNotFinite()
Additional Information:
(none)
Did you read what this error message says? If you didn't understand it,
did you try to look up the numbers::is_finite function and the
ExcNumberNotFinite exception? They're here:
http://www.dealii.org/developer/doxygen/deal.II/namespacenumbers.html#aecd64881824be539b5707a983c880498
http://www.dealii.org/developer/doxygen/deal.II/group__Exceptions.html#ga9c63dc4bbb83dc9ae475713e305bb76f
void dealii::SparseDirectUMFPACK::factorize(const Matrix&) [with
Matrix = dealii::SparseMatrix<double>]
The violated condition was:
false
The name and call sequence of the exception was:
ExcNeedsUMFPACK()
Additional Information:
(none)
Here, ExcNeedsUMFPACK is described here:
http://www.dealii.org/developer/doxygen/deal.II/group__Exceptions.html#gac7ba25d5b3e289abc52ff0386bd8cb4e
You spend a great deal of time explaining what exactly you get from your
program, expecting others to explain it to you. You need to learn to
spend some time on reading error messages, and reading up on things you
don't understand.
Best
W.
