Hi I don't know if this will help you, but I am presently dealing with an induction motor and I am also rotating the rotor. Maybe this example is of help Example (I did this in the pre-processor, but it can just as well be done in the post-processor) To select point (10,10) which is rotated about point (0,0) The amplitude is in this case equal to sqrt2*10 = 14.14 and the angle is 45 degrees rotation_angle=0 x=14.14cos(45+rotation_angle) y=14.14sin(45+rotation_angle) selectnode(x, y) One can also select arcsegments or lines in the pre-processor. What I did in the post-processor to get the flux-density in the air-gap was to use the command "selectpoint(x,y)" and select the ends of a an arc-segment that was placed in the centre of the air-gap. It then selects the whole arc. ----- Original Message ----- From: Mihai Priboianu To: femm@yahoogroups.com Sent: Friday, May 09, 2003 10:46 AM Subject: [femm] Lua script Hello ! I'm making a Lua script for evaluate the flux density distribution in the airgap of a 12 pole permanent magnet synchrounous machine. In order to reduce the solving time I must analyze the problerm only for a pair of poles so, I must use Periodic BC's. For that reason, I'm rotating the rotor with 1 electrical degree (1/6 geometrical degree). I put that in a for statementin a Lua script. My question is: Is there any way to select a segment in the postprocessor without specifying the points coordinates ? Attached you''ll find the geometry of the machine ! Thank you !!!
