HI
I HAVE WRITTEN A 2D UNSTRUCTURED EULER SOLVER. IT USES TRIANGULAR MESH, READS THE MESH IN COBALT FORMAT, WRITES THE OUTPUT IN TECPLOT CELL-CENTERED FORMAT. IT CAN DEAL WITH ONLY 2 BOUNDARY TYPES AS OF NOW- FARFIELD AND WALL. SCHEME USED IS ROE'S SCHEME. I HAVE RUN IT OVER A NUMBER OF TEST CASES AND FOUND SATISFACTORY RESULTS. COULD SOMEONE TELL ME IF IT CAN BE OF ANY HELP TO CFD-ONLINE.COM? DO U SUGGEST SUBMITTING IT TO THIS SITE? PRAPANJ |

Well,
I have solved, 1. subsonic flow over RAE2822 airfoil, transonic airfoil 2. transonic flow over the same 3. flow over wedge(15 degree) (oblique shock) 4. prandtl meyer expansion over 15 degree convex corner |

If you used the explicit time-stepping, then your code is of the same category as NSC2KE open code by B. Mohammadi. If the time-stepping is implicit, then your code might be of interest to CFD community indeed.

Nowadays, I am also solving test cases. I have solved following test cases:
1. rearward step, 2. blunt body and 3. compression corner 7.5 degree all are high supersonic. I am interested to solve your test case 3 & 4. may you please provide me their reference. I am using Harten-Yee TVD and ACM schemes. we may compare our results with experimental data and could make some conclusion. Hoping positive response from you. cfdxue |

Which method do you use in your code? Finite volume?
If you use finite volume without reconstruction technique , you have first order accuracy. Therefore if you want to take more accurate results you must do very dense mesh in high gradient regions. Also you haven't problem with shock capturing due to the monotonicity of all first order schemes. |

it seems like your numerical method is FVM am I wrong? I'm very interested in TVD schemes and would like to utilize it in different numerical methods. If you both were cfd-online users we would exchange some Experiments etc |

I am a new learner who is writing a 2D EULER SOLVER. I use the Finite Volume method,and Jameson's central scheme But I have some questions in farfield boundary conditions. Many thanks! ljnpu@foxmail.com |

I apply the hybrid FVM-LBM to solve the Euler equations, but i have some troubles in the computation of the gradients in boundary. Thank you very much! 229344870@qq.com |

Hello,
I am coding a 2D euler code with Roe flux in a turbine blade passage. The roe flux on its own works perfectly (specifying a single left and single right state). however when implemented in the turbine blade solver and looping over the edges of a cell, the residuals go to NaN.. Could you please tell me why this happens/ Thx |

Prapanj,
In your 2D Euler Roe scheme, are you solving 1D (3 eigenvectors) in each x and y directions (decoupled), or are you solving the 2D Euler equation coupled x and y? I should mention that I'm solving this on a structured grid. Thanks |
