Hello Everybody,
I am interested in simulating and visualizing the shock waves in the air with propagating spray. Could anyone simulate and visualize a shock wave with Star-CD? Thanks |

Sure you can simulate a shock wave - Star-CD Validation Test Cases pack has an example of shock tube simulation.
For visualization I can recommend plotting magnitude of density gradient (or density gradient squared - you can try what looks best). When plotted in grayscale it can give you nice Schliren-like pictures. Or you can plot an isosurface in 3D. |

Thank you very much Anton,
That's exactly what I was looking for. And please advise, where can I get Star-CD Validation Test Cases pack? |

I've got it from my Star-CD vendor, it occupies 1 CD. I don't have it at hand right now to tell you the size of the shock tube case - may be I'll be able to send it to you via e-mail.

When you say i need to plot the magnitude of density gradient (or density gradient squared), it means that I first calculate the density, as one of my scalars, and then in post processing I calculate density gradient (or density gradient squared) and plot it in Registar 4, then I plot it in grayscale and get Schlieren like images. Is it correct? Thank you so much |

Yes, you're right. BTW, I've found my Validation Test Cases CD. The shock tube example takes only 150 Kb when compressed

I would really appreciate if you send me the shock tube example file to this e-mail: cadcamclass@gmail.com Thanks a lot |

Ok, I've sent it. It's a simple 1D case, so don't expect much from visualization point of view, it's just to demonstrate simulation procedure.
