Meshing an impeller

Meshing an impeller

Meshing an impeller

(OP)
Hi,

I am trying to mesh an impeller however I'm having trouble trying to figure out the correct procedure for this. Would anyone be able to recommend how I should be meshing an impeller, the cone shape and perhaps the fins..

Regards

RE: Meshing an impeller

I would defeature it first by getting rid of those little welds and the shaped ends of the fins. I've never seen the point of modelling welds as I've yet to meet a welder who can weld so perfectly. You would then have rectangular type shapes which could be meshed using brick elements.

RE: Meshing an impeller

If computational time is important, then it could be an option to mesh the fins with shell elements. Cone with hex or tets.

RE: Meshing an impeller

personally I wouldn't defeature the rads ... if I can live with a bazillion elements ... so it might take a day to solve ?

it depends on the fidelity of the answer. replace the strakes with mid-plane 2D elements sure (about the same as defeaturing. you could model the hub with 2D elements too.

but the cost of 3D elements is low, so why ?

another day in paradise, or is paradise one day closer ?
