FloXpress - not so fast
FloXpress - not so fast
(OP)
I mean, not so fast getting started.
First, I had to make a model that was seamless.
Okay, that's out of the way.
Now, I'm trying to specify the inlet conditions.
But with the >required< caps in place, I can't seem to tell FX what face is to be the inlet face. I keep getting the message "The selected face does not contact the fluid or it is external face of the model."
... and that's as far as I got.
The help is abysmal even by SW standards.
Anyone?

Got it. Okay, stumbled on it.
You have to HIDE THE MODEL so you can click the face of the plugs. I think that's just a little counterintuitive.

RE: FloXpress - not so fast
I am using a trial of FloWorks and it is defiantly a whole bunch better. You can actually view your mesh!! I am not sure if I would ever trust FloXpress for any real project because you barely know what is going on in the background. I did find that if you adjust the "Smallest Flow Passage" it does indirectly affect the mesh. So I used that for my sensitivity studies. I hope this help.

I was mostly interested in a rough delta P, which is not reported, to see how much of the backpressure budget is consumed by the one part.
So I ran it with a not quite arbitrary flow, the nominal system flow, which reports a velocity.
Then I ran it with a not quite arbitrary delta P, the system backpressure limit, which reports a considerably lower velocity.
I think I can safely infer that the part is too damn small.
Color me disappointed. The 'report' produced by FloXpress is not nearly zoomy enough to make a case for nearly doubling the cost of a seat.

I'm saying it's not strong enough to catalyze an up-sell.
Not here anyway.

With FloXpress you basically have to completely black box your analysis because of limited reporting tools, mesh viewing, refinement and inputs. In a magic 8 ball at least you know your odds.
Test and correlate often if this is for anything critical.
