Asking for help solving Meshing Failed issues

Component 5, (Nacelle_Top) and Component 7 (Nacelle_Bottom) are experiencing failure to mesh. Can you take a look? It might be obvious to you.

Here's a download

Component Topology Better This Time

The previous iteration of this TCAE project experimented with omitting a central component from the topology, the Duct_Separator, going from the Top_Fan rim (sometimes called a hub, in this case an open

Project setup has errors but cannot tell what or where

Working through the Check for Errors exercise finally presented only this orange border in the Components Map. Other than TCAE Output messages, there's no textual description of what or where things have gone awry. I'm assuming it's displayed somewhere in the TC...

I am loving this!

Still working through the Check exercises. Narrowing the errors down (hopefully!).

Making Progress!

That I've gotten this far, in my estimation, is cause for celebration. 5-lime margarita time!


(they only yielded 4 oz. of juice from those small organic limes, but it'll do).

Patch connection problems (solved)

I'm amazed at the Check functionality. I've been eliminating one similar error after another until now.
From the directory for the component named "Top_Fan", I copied and pasted an interface patch (.stl) into the directory for the component named "Hull__Inlet__Outlet", same file name, same type: "outletInterface" with the intention t...

Twin Centrifugal Fan Component Map

A common inlet at the top feeds two (identical) centrifugal fans. I tried to connect Top_System_inlet_interface (identical to but different in name as suction outlet interface) to serve double-duty as outlet interface to both the Top_Fan (rotating) AND Bottom_Fan (rotating).

It seemed that wasn't working so it occurred to me that connecting a copy of the object with another name might. Su...

The CFDSUPPORT ChatBot suggested steps for creating two meridional slices, one for each fan in TCAE

The instructions are as follows:

To create two meridional slices, one for each fan in TCAE, follow these step-by-step instructions:

I'm seeing two color bar legends in Reader View, one overlaying and obscuring the other.

After reimporting surface geometry, I see that the legend for the color bar in Reader View has multiple color bar legends superimposed. Can I, should I hide one or the other?

If so, how?


Thanks,


David

Bottom_Fan_Bottom_Duct_Surface out of position (too low).

I'm not wanting to re-import geometry, although that's most certainly what I'm preparing for at the moment. All the STLs were created using the _ExportWithOrigin command with World origin as basepoint in Rhino, so I'm scratching my head, as usual. Importing the offending object back into a "top" drawing, an assembly-of-all-parts model, and aligning it to it's exact position, then re-exporting i...
