Hello,
After a libMesh update, I have to adjust my code to the
explicit/implicit separation in RBEIMConstruction. Now, in my overridden
function of RBEIMConstruction::truth_solve I get an error at the
following line:
rhs->add_vector(context.get_elem_residual(),
context.get_dof_indices());
The crash happens at the line:
if (!v.empty())
in the function add_vector (see debugger below).
If I convert context.get_elem_residual() from a DenseVector to a
std::vector, I do not have any error. If I run RB-example4 (EIM), there
is also no error.
Can anybody see what is going wrong with my DenseVector?
Thanks!
Lorenzo
