Thanks Prof. Bangerth for the suggestion. I will definitely learn about the debugger as it seems like a great tool.

Krishanu, indeed, Bruno knows this because he is looking at the backtrace shown in the error message you posted: #0 ./nodal_growth_dyn_full: Step8::ElasticProblem<1>::assemble_system_matrix() #1 ./nodal_growth_dyn_full: Step8::ElasticProblem<1>::run() #2 ./nodal_growth_dyn_full: main The easiest way to find these errors is to run the program in a debugger. It will stop in exactly the place where the problem is, and allow you to inspect all local variables. It's a tool so worth learning how to use! (There are also video lectures showing how to do that in eclipse.)

No it's not where the error comes from. It is from somewhere in
Step8::ElasticProblem<1>::assemble_system_matrix() You need to find
which line produces the error.

[deal.II] Re: Issue regarding higher order element
Hello Bruno,
Here is the error message that I am getting:
An error occurred in line <388> of file
in function
dealii::Tensor::value_type& dealii::Tensor::operator[](unsigned int) [with int rank_ = 2; int dim = 3;
Number = double; dealii::Tensor::value_type =
dealii::Tensor<1, 3, double>]
The violated condition was:
i::assemble_system_matrix()
#1 ./nodal_growth_dyn_full: Step8::ElasticProblem<1>::run()
#2 ./nodal_growth_dyn_full: main
CMakeFiles/run.dir/build.make:57: recipe for target 'CMakeFiles/run' failed
make[3]: *** [CMakeFiles/run] Aborted
CMakeFiles/Makefile2:232: recipe for target 'CMakeFiles/run.dir/all' failed
make[2]: *** [CMakeFiles/run.dir/all] Error 2
CMakeFiles/Makefile2:239: recipe for target 'CMakeFiles/run.dir/rule' failed
make[1]: *** [CMakeFiles/run.dir/rule] Error 2
Makefile:183: recipe for target 'run' failed
make: *** [run] Error 2
I am using deal.ii for a nonlinear elasticity problem. And the change in
the code that is causing this error message is:
template
ElasticProblem::ElasticProblem ()
:
dof_handler (triangulation),
fe (FE_Q(3), dim)
{}
The code runs fine when I am using FE_Q(2) or FE_Q(1) instead.
Thanks,
Krishanu

[deal.II] Re: Issue regarding higher order element
Krishanu, It's impossible to help you with so little information. Somewhere you set something to the wrong size. Can you give us a backtrace? We need to see the error message and the code that produces it.
