Is there a more in-depth version of your tutorial? I can't seem to get the workbench setup that you have. I can't get two Mesh 'blocks' to connect to a single CFX one like you have (0:09)
Hi.. In order to add two meshes to a CFX block you need to drag and drop each mesh to the setup... First click and drag the stationary "Mesh" (B3) to the CFX "Setup" (C2), second click and drag the rotating "Mesh" (D3) to the CFX "Setup" (C2).. It should add both meshes to the CFX block.. I hope that helps.. Let me know if it doesn't...
@@simplecfd2006 That worked great, thank you very much for your help. I'm having to conduct CFD on a Savonius rotor for my MSc Dissertation/Project, this video and your support have been a huge help!
That of course depends on your angular velocity... In my example it is set to 5 [rev/s].. We can then calculate 5 [rev/s] * 360 [deg/rev] = 1800 [deg/s].. From here we can calculate for example the 10 degree timestep by (10 [deg])/(1800 [deg/s]) = 0.00555556 [s]... However, the time entered at 3:10 is not the simulation timestep, but the transient results export timestep.. The simulation timestep is defined at 0:22 and set to 0.0002 [s],
I just downloaded the Software and I don't even know how to Import something. Could you do a tutorial for noobs? I can't find anything usefull that goes over the basics of the basics. Am I even able to import STL-Files??
Hi Carlos.. STL-files are not very suitable for Ansys Workbench... You can import an STL in SpaceClaim, but you may need to do a thorough clean-up to make it suitable for meshing/simulation. If you can get the geometry as step-file or even better a full CAD format, you'd be much better of...
@@simplecfd2006 Hi there Thank you so much for the answer. I have gone back and forth trying to learn CFD and to be honest I am just about to give it up. Learning CAD really was straight forwards but i struggle with CFD. I will give it a try with an other file format.
Need the geometry dimensions

Another question for you, how would I set up the time-steps so that for each time-step, the object rotates 1 degree or 10 degrees? 3:10
