[Fluid] Standarize buffer filling

11

**📝 Description** This PR (finally) makes the buffer filling of the `FluidDynamicsApplication` solvers properly, that is to say _à la_ `StructuralMechanicsApplication`. As you note, what we basically do is to...

[Fluid] MPC-based slip condition

12

**📝 Description** This PR adds support for MPC-based slip boundary conditions. In front of what we did so far to apply the slip BC (by rotating the system of equations)...

Compiling Kratos with `pypy3` yields an error in the Python exportation of the logger. The issue is located in `add_logger_to_python.cpp`. Specifically in https://github.com/KratosMultiphysics/Kratos/blob/96cc60fd5784600c5a6068e23b42aa9a9c8a3d5a/kratos/python/add_logger_to_python.cpp#L77 Seems to be something related to the...

[Fluid] Skip replace elements&conditions if geometry-based input modeler is used

1

**📝 Description** With this PR we will skip the elements and conditions replace done by the `ReplaceElementsAndConditionsProcess` for the `use_input_model_part` option in the I/O. Note that this is aligned with...

**📝 Description** Both the `assign_vector_by_direction_process. py` and the `assign_vector_by_direction_to_entity_process.py` were directly calling the `CalculateOnSimplex` when computing the normals. This of course turned into an error when using non-simplicial geometries. With...

[PfemFluid] CutFEM element

1

**📝 Description** This PR adds a CutPFEM Navier-Stokes element together with its required functionalities.

[Geo] Orchestrator-based multistage

3

**📝 Description** This is a draft PR for the discussion of the more delicate changes required for the upgrade of the current multistage capabilities of the `GeoMechanicsApplication` to use the...

**Description** In the `UpdateStressStrain` of the 2-step v-p strategy of the `PfemFluidDynamicsApplication` the `InitializeSolutionStep` of the elements is called as https://github.com/KratosMultiphysics/Kratos/blob/bba1966863454d23e6368da083db81ff3fe64df1/applications/PfemFluidDynamicsApplication/custom_strategies/strategies/two_step_v_p_strategy.h#L312-L330 Such function is called at each nonlinear iteration from...

[Fluid] Add CFL output

5

This issue is a reminder to add the new CFL output capability in a similar manner we did for the drag one. The plan is to do this after the...

New GUIs (after 8.1)

1

This is just a reminder of the new developments that we need to add to the GUI after the 8,1 release - [ ] Explicit convection-diffusion elements - [ ]...
