Thank you for your suggestion Prof. Bangerth. I was able to pinpoint the
problem in my code. I am trying to write all the stress and strain
components to the output *vtu files. Below is how initialize the variables
needed for that before filling them up with quadrature point history. The
lines of code in red are where the memory error is arising from. Is there a
better way of handling this process, or am I making some fundamental
mistake?
//Output stress and strain componenets
std::vector<std::vector<Vector<double>>> history_field_stress(dim,
std::vector<Vector<double>>(dim)),
local_history_values_at_qpoints(dim, std::vector<Vector<double>>(dim)),
local_history_fe_values(dim, std::vector<Vector<double>>(dim));
std::vector<std::vector< Vector<double>>> history_field_strain(dim,
std::vector<Vector<double>>(dim));
for (unsigned int i=0; i<dim; i++)
for (unsigned int j=0; j<dim; j++)
{
history_field_stress[i][j].reinit(history_dof_handler.n_dofs());
local_history_values_at_qpoints[i][j].reinit(qf_cell.size());
local_history_fe_values[i][j].reinit(history_fe.dofs_per_cell);
history_field_strain[i][j].reinit(history_dof_handler.n_dofs());
}
Thanks in advance,
Raghunandan.
