CG/UGflow

In CGflow one can create geometry on your own in this GUI, mesh it and run the simulation with appropriate physics models. The following models will be available for now,

Current models:

Single Phase:

1. Steady and unsteady explicit method (Coupled approach only)

2. Liquid (Constant density), Ideal gas

3. Inviscid, Laminar and Turbulent flow regimes

4. Turb models: K-Omega wilcox, K-Omega SST

5. Wall Functions: Low Y+, High Y+, All Y+

6. Overset method (For now stationary and translational motion only)

7. You are free to select HLL, HLLC, E-CUSP, Steger warming, Van Leer FVS, ROE FDS, AUSM, AUSM+ , AUSM+ -up, MacCormack and LaxWendroff.

8. You are free to run your simulation in First order, Second order (With and without limiter functions). Minmod, Koren, Superbee and Sweby limiters are available. Flux limited approach and MUSCL approach.

9. Available both in Finite difference. For now with this GUI you can run 1d and 2d simulations. MPI under progress for 3d simulation.

Multiphase:

1. Volume of fluid - SOLA-VOF (Hirt and Nichols Donor acceptor scheme)-2D

2. MAC (Marker and cell method)-2D

3. Incompressible NS Chorin projection method

UGflow

UGflow is an unstructured triangular grid, Median-dual cell finite volume solver. For this you have to import the mesh file as specified in the help.

Current Models:

1. Steady and unsteady explicit method (Coupled approach only)

2. Liquid (Constant density), Ideal gas

3. Inviscid EULER, Laminar NS

4. You are free to select ROE, HLLC schemes for now.

5.Residual smoothing is implemented

6. You are free to run your simulation in First order, Second order (With and without limiter functions). Minmod and Venkatakrishnan limiters are available. MUSCL approach.

7. For now with this GUI you can run 2d simulations. MPI under progress for 3d simulation.

GUI will be used to launch the serial and parallel exe's based on the input specified. Post processing will be in the same GUI.
