Bug in GenerateElementVector
There is a bug in m_fields->GenerateElementVector function member for parallel runs. The bug is isolated and illustrated in the enclosed solver. When we run the solver for the test case in the serial mode we get the value area is 3.5 for area, but in the parallel run with 2 processors (np = 2) we get area is 1.5. The solver is just ADRSolver in which m_fields->GenerateElementVector is hard coded, with exactly the same test case.
