Hello
I have two vertical-axis wind turbines (2D) separated by a certain distance, rotating about their own axes. I'd like to monitor the moment coefficients of their airfoils individually. I know I can do this through the Moment Monitor Dialog Box, but it doesn't allow me to choose different moment centers. Obviously, the two turbines are not rotating about a single point, so I'd like to know how I can specify two points instead of just one. Please help! Thanks a lot in advance. Ali |

Ali, create two separate Moment Monitors. You can then specify the axis individually for each monitor.

Looks like it has to do with the version. I'm using 12. The Migration Manual for 14 says this is a new feature: Quote:

Yes, I can print the monitors per zone, but the axis for one will be wrong. And I don't want to do the computation twice. Hmm.. parallel axis theorem. Rings a bell. You think that'll work for this? I'll have to go read up on that. |

It'd take me around 36 hours to get the complete computation done. So I'm just trying to solve for the first 10 iterations or so, and will then try to get a correlation between the moment coefficients.
Thanks a lot for your help. Appreciate it. |
