Naca 0012 mesh file

Right, the NACA airfoils do not have a sharp trailing edge; this is on purpose because real airfoils do not have zero thickness edges. If you want a sharp trailing edge, you have to do some modification.

There are no rules on how to modify it because modifying it makes it no longer following the NACA contour. Hence there is no valid DAT file that has a sharp trailing edge.

Thread Tools. BB code is On. Smilies are On. Trackbacks are Off. Pingbacks are On. Refbacks are On. Forum Rules. No options are required for this mode.

Alternatively, the user can specify custom reference values in order to separate the initialization and non-dim. This information is useful for verifying that the desired non-dim.

Instructions for running this test case are given here for both serial and parallel computations. Follow these steps to run the case in parallel:. Results for the turbulent flow over the NACA are shown below.

The computed SU2 solutions are in good agreement with the published data from Gregory. In addition, the computed values for Cp and Cf for both angle conditions are nearly indistinguishable from the CFL3D results. Improve this page. Toggle navigation. Getting Started. Be aware that will we also change our viscosity value to adjust our Reynolds number to 6E6. There are a few numerical solver specifications necessary before we can run the calculation. The following video shows you what specifications will likely make for a verifiable, converged solution.

Double-click front in the Select dialog and select Color Map to create contours of pressure coefficient. Since the initial Cp value is 0 everywhere, no contours will be shown until the the simulation is run.

Drag and drop the Cp Plot tab over to the right-hand edge of the Caedium application window to split the window into two parts as shown below. Double-click volume in the Select dialog and select Monitor to create the residuals monitor. Drag and drop the Residuals tab over to the right-hand edge of the Caedium application window to split the window into three parts as shown below.

After each simulation time-step equivalent to iterations by default the results will be refreshed. For this simulation you will increase the number of simulation time-steps to 30, for a total of iterations.

Right-click on the View Window view background, double-click sim , and then select Properties from the menu. Select the Simulation tab in the Properties Panel. In the Home Toolbar click the Run button to run the flow solver. If you wanted to interrupt the flow solver, you would re-click the Run button; the solver would then stop at the end of the current simulation time-step.

Let the solver complete its run. Note the updates of the Cp contours, the Cp plot, and the residuals monitor as the simulation progresses. This airfoil simulation is very nice. Is it possible with Caedium to produce native 2D simulations without importing an externally generated special mesh? Is it possible to do this for another airfoil yet? The last time this was asked was over a year ago so I'm hoping it is :.
