[deal.II] ASPECT 2.1.0 released

2019-04-30 Thread Rene Gassmoeller
We are pleased to announce the release of ASPECT 2.1.0. ASPECT is the Advanced Solver for Problems in Earth’s ConvecTion. It uses modern numerical methods such as adaptive mesh refinement, multigrid, and a modular software design to provide a fast, flexible, and extensible mantle convection

Yes, it looked like not enough precision of numbers and thats why it quantisizing mesh to grid. I am using VTK and standard workflow from step-6: DataOut data_out; data_out.attach_dof_handler(dof_handler); data_out.add_data_vector(solution, "solution"); data_out.build_patches(); std::ofstream

Sorry, if my question(and english language) is not clear enough. Yes those "triangles" mesh are what I call "disordered mesh". By design, my mesh generator produces only quadrangular elements(with area nearly 1e-10), but after few refinments in deal.ii paraview shows those pictures: one
