Rotation of a factory around the global Z-axis with rotation of the velocity parameter(Direction).

Hello all,

I would like to shoot water particles at a tube filled with particles. For this purpose, small holes are embedded in the nozzle geometry where the factories are positioned. The holes/factories have a defined angle from which the particles should come out with a certain velocity. When the nozzle starts to rotate, the angle remains fixed and does not rotate with the nozzle. Is there a possibility to let the angle rotate with the nozzle ?

In the picture you can see the rotation of the nozzle and the coordinate system of the factory. The particles should be generated along the Z-axis and start rotating when the nozzle does.

 

Thank you in advance

    Hi,

    I don't think it's possible with a regular factory, unless I'm forgetting some functionality. You can define the rotation easily enough with local/global axes but this concept hasn't been extended to factory velocities yet.

    If you want particles to leave at angles that rotate around a common axis then I think you'd be better off with a custom factory, where you have complete control over the linear/angular velocities.

    To add to Richards comment as he says it's not possible currently to set the factory velocity to be normal to the plane, it's a nice feature to have though which we've highlighted to the product team.

     

    There is a factory API tutorial here - https://community.altair.com/csm?id=kb_article_view&sysparm_article=KB0115860 which could be a starting point for developing your own factory.
