Hi, Reef3D CFD has an option for writing velocities in a fixed point to file. I want to compare to Reef3D FNPF, but there it is not possible to extract, one has to watch the movie. Is there a way to read the movie file, and get numbers, so that it is possible to compare the velocities from the two programs?
Best regards, Anne Katrine Bratland |

Hei, yes that is sadly currently not possible inside REEF3D.
However it is possible to use ParaView to get the velocity data for a point as a time series. You could place a probe (Filters/Data Analysis/Probe Location) at the position and then plot the data over time using Plot Data Over Time (Filters/Data Analysis/Plot Data Over Time). The resulting graph can then be saved as a .csv, with the value being located in the avg(variable) field. Hope that helps. |

Now available in the new master 24.02. Also added a new tutorial case for REEF3D::CFD on how to use the probes for the case of 5th-order Stokes waves. See the User Guide, tutorial case 10.9.
