Weird curtains and wind

I made some curtains and linked them...I put them up and then I had to move them to the other side of the door frame because the wind was blowing them through the doorway (south)..but once I changed sides, now the ends are flowing back through the wall (north)..... and really I reduced the wind so much they should not be moving at all anyway. I am a real newbie at this...this is my second project.

Thanks,

Update...I think I need a script to keep the curtains from blowing in several diff directions.

You can't control the direction prims are blown by the wind. You might want to add a script to apply a force along one axis of the prims based on the current version of llWind().

You don't have any control over which way the wind blows in SL, and it changes direction and velocity all the time. You have to strike a tricky balance, sort of the way you do with a curtain in an open window in RL. You want curtains to have some response to the wind so they don't just hang there looking stupid, but you want it to be subtle. Most people set the Wind parameter in flexi way too high -- fine for flags, but not for most curtains and skirts. I usually set it a 0.5 or 1.0 unless I'm really trying for a windblown look. You can exercise a bit more control by maximizing the Gravity parameter and adding a big Z force. That's sort of like sewing lead weights into the hem of a curtain to keep it from blowing too much. Mess with Drag too.

Yes, you could theoretically write a script that uses llWind to detect the local wind vector and controls the flexi properties of the curtain dynamically, but my guess is that it wouldn't be worth the trouble and might cause a lot of load on the sim anyway. It's wiser to just play with the flexi parameters manually until you get something that looks reasonable.
