How do I cover holes for FloXpress in my assembly of parts?

K. N Jul 18, 2014 1:02 AM

Hello!

I keep getting warnings everytime I try to use FloXpress in my model. It's a showerhead, and basically I keep getting messages like "The geometry is not ready for the flow analysis." and "The model openings must be closed with lids." How do I find the cavities I need to cover? Also, how do fit the lids to some of the cavities? Some of the visible holes have a unique shape, so I covered them with rectangles, but the FloXpress is not working. I'm very sorry if this is a no-brainer, this is my third day of using Solidworks, so I'm not very sure how to use this feature and how to deal with these messages. Thank you!

Hi K,

No worries. In FloXpress you do need to make sure your entire "computational domain" is enclosed. There is a lid feature but that only works well with planer geometry. If you have a complicated hole, you may need to make a custom plug to fill that hole.

Also keep in mind that a hole is not filled if your lids only meet at edges. A lid is only valid with overlapping volumes or touching faces.

This can be a frustrating task to complete if you have complicated geometry which is why I suggest simplifying the model if possible.

All the best,

what do you want to do in this analysis? even if you fix the lids, if you want to see how the water comes out of the showerhead, that isn;t something even full flow simulation can do.
