3D Cross-flow turbine dynamic mesh error...

SonicGhoul · March 6, 2014, 01:55

Hi, i'm beginner. Thank you for any information. help me.

latest, doing Cross-flow Turbine simulations with fluent..

But dynamic mesh's problem occur..

UDF code is no problem..because using the simple code in tutorial..

I guess.. Remeshing problem at around blades.

I create small Tetra mesh nearby blades for viscous boundary layer..

During simulation, the water came from entrance nozzle..

then water hit the blades, and rotating the rotor.

But rotor is not even half a turn by error.

Some Enginner's talk to me.

He said, " Create more small size meshs nearby blades, Need becoming smooth surface ".

is that solution right??

Thanks all kindly
