SubscriberI have disect the geometry into parts, so that I can do sweep meshing,
I can do sweep mesh as you can see on the photo, and the mesh quality also good.
As my body has multiple parts, I have used share topology which I have enabled from the component property. But when I try to do mesh, I saw all the bodies aren't sweepable.What is the reason of this??
How can I resolve the issue??
I couldn't not add inflation in my geometry, when I select the whole body in the geometry scoping method, it shows "x" on it's left side, you can see from the first picture.
How can I add inflation and do the hex mesh??
I have tried watertight meshing with the disected body and not used share topology in space claim, but in watertight I have used the share topology
 option and do the poly hex-core mesh, I have also add inflation from boundary layer and after running simulation it show "0 flowrate from the outlet", I have used pressure inlet when I input gauge pressure= 0Pa, and at pressure outlet, gauge pressure= -4000Pa, it has to come 60-63L/min flow rate from the outlet. -

Forum ModeratorI've already answered the meshing part - multiposting tends to slow response time as we need to clear up duplicates.Â
If you've set pressure in and pressure out but there's no flow on the outlet check the domain for stray walls: you may have a mesh disconnect somewhere that's preventing flow. If you plot a pressure contour across the domain (on a plane/isosurface) is there a sudden change in pressure anywhere?Â

SubscriberYes I have tried to see the pressure drop on the body with the share topology activated body, there is not any sudden change.
Â
Also, with out share topology geometry I have tried simulation but the flow rate isn't coming accurate. Do I actually need hex mesh?? Or I have to check the boundary condition again??Â
