Issues when using Flow Simulation
9 months ago



I am trying to test the efficency of a Propeller I have modeled up using Flow Simulation. I have watched a few youtube videos (both in a langugae I do not speak) and tried to just follow the visuals. After copying both of their settings and trying with my propeller, both are giving me the same issue:



I attached my files, if you could see where I am going wrong that would be awesome.


Basically I just want to see the Flow Trajectories so I can make changes in the design to help it spin.

Hi Matthew,


It looks as though it's struggling to create a mesh for the singularity that you have at the end of the cone. Once I cut this off meshing completed successfully. (see image below)


Without the feature history its difficult to see how this was produced, but a revolve with a small radius at the tip should work for you without affecting the results of the sim.

Re: Issues when using Flow Simulation

for flow analysis, the fluid volume needs to be generated (i.e) the area inside or outside in which the flow is required.. this generated volume is fluid volume.

for creating the fluid volume remove the unwanted parts in the assembly, to make it simple and solve fast.
