I HAVE WRITTEN A 2D EULER SOLVER
HI
I HAVE WRITTEN A 2D UNSTRUCTURED EULER SOLVER. IT USES TRIANGULAR MESH, READS THE MESH IN COBALT FORMAT, WRITES THE OUTPUT IN TECPLOT CELLCENTERED 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 CFDONLINE.COM? DO U SUGGEST SUBMITTING IT TO THIS SITE? PRAPANJ

Hi
which TEST CASES have you solved....?? cfdxue 
Re: I HAVE WRITTEN A 2D EULER SOLVER
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 
Re: I HAVE WRITTEN A 2D EULER SOLVER
If you used the explicit timestepping, then your code is of the same category as NSC2KE open code by B. Mohammadi. If the timestepping is implicit, then your code might be of interest to CFD community indeed.

Re: I HAVE WRITTEN A 2D EULER SOLVER
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 HartenYee TVD and ACM schemes. we may compare our results with experimental data and could make some conclusion. Hoping positive response from you. cfdxue 
Need a 2D euler solver
hii...i have just started to learn cfd....i need a 2D euler eqn solver..plz post if u hv one

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 cfdonline users we would exchange some Experiments etc ;) 
I need your code to study

Would you please send me a copy?
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 FVMLBM 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

2d Euler turbine blade passage
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
