[DesignModeler] Design modeller problem with direction vector

katarzyna · January 9, 2013, 08:23

Hi,

I am a begginer using ansys software, and I am trying to set up a model of a mixing tank.
I have a problem in design modeller. I draw a impeller with blades at 90 deg, but now I want to have them sloped at 45 deg. I do not know how to do it. I suppose it would be possible to change the direction of the vector while executing extrude operation. Could anyone explain how to do it?
I have attached my design - the green part is the blade that I want to slope.
Thanks for help.

Although I haven't worked on similar projects recently, I don't think this should be too difficult to achieve in Design Modeler. First try to create a sketch in a plane perpendicular to the vertical axis. This also allows you to sketch the blade at the desired angle in cross section. Then simply extrude this in the axial direction.

If you want the blades to have more of a helical profile then it may be a bit more difficult. Do you have a sketch or image of the type of geometry you want?

Good Luck

try body operation -> rotate....

Thank you Crank-Shaft this solution worked.

I wonder why have I not come up with this!
Diamondex - this option didn't work - I could not rotate the blade in a direction....
Thanks for reply.

No problems, glad I could help.

Post the images of your final geometry here. I am interested to see what you managed to create.

This is the final design of my stirred tank. I draw the blades in XY plane which allowed me to easily operate with the angle of the sketch and then extruded it in Z direction.
Another thing was appropriate meshing of the system...the area around the stirrer is the moving frame, but after long hours I managed too!

I have to say it was kinda tricky for a begginer.
Thanks again for help!!!

That looks great.

I am relatively new to Computational simulations too and I personally would find it quite difficult to mesh. It is amazing what we can learn over time though and I wish you all the best with your work.

Can somebody assist in having a UDF for slug length in air-water T-junction microchannel.
