don't know.
I don't know... Perhaps ask on the the Fluent Forum or perhaps contact your friendly neighborhood tech support.

Nastran format is your weak link...
Maybe someone else can help you move forward, but I can tell you that Nastran does not support hanging nodes. I don't know about SYSNOISE...

1) To define materials, right click on the Parts branch of the model tree to either create a new part or add to an existing one (only add to parts reserved just for volumes or you will have boco...

One more thought...
One other thought… The above plan will work “after” your ogrid around the mirror… but it could probably be better to do it before the OGrid around your mirror. If you do the mirror boundary layer...

Almost there.
Great, almost there…
Two more steps and you will have a great mesh…
1) Move your verts onto your geometry. Yes, it looks ok without moving it, but later steps (such as OGrid...

Topology isn't right.
Your topology isn't right...
You have your OGrid connected to the plate with the Mirror sticking up into the OGrid blocks. This gives you awkward mesh at the "corners" of the sphere again, but...

Not an ICEM CFD Dealer
Hey Alex-fan,
I thought you were already using ANSYS ICEM CFD when you added your question to this thread. I can’t send you software, it would be more than a Gig and you would still need a...

No Face with Given Nodes.
To Alex-Fan,
Your error message "no face with given nodes."
Usually means that you have "uncovered faces". you can do this check in ICEM CFD to be sure.
It just means that you have volume...

One more ogrid.
One other suggestion,
To capture the roundness of you mirror you will need another OGrid that I didn’t include earlier.
Imagine that you have two mirrors back to back. Create a split...

Practice.
You are seeing the cumulative effect of a variety of errors.
To do it well, I would recommend starting over. Do it just like the sphere cube tutorial, plus some of the suggestions I gave, and you...

2 Ogrids...
Starting from Wieland’s geometry/blocking and moving forward (including with the strange FF and VORFN issues)…
It was time for the new OGrids… I could have done it as one Ogrid, but then the...

Took a look.
Hello…
Ok, Wieland sent me his model and I took a look.
The first problem is that you had 4 to 1 refinement… I have never seen that working with Fluent. Try 2 to 1 instead. (I...

Give OGrid another try some time...
OGrid really will work very easily for this model and dramatically improve your quality...
It really is one of the key tools in ICEM CFD hexa. Not using it would make me feel like a carpenter...

OGrid...
Yes, Certainly. To fix this you need to apply an OGrid... You are trying to fit a square peg in a round hole and the corner elements are opening out to approach 180 degrees.
If you have access...

Don't use that global smoother at all.
You probably shouldn't be using that global smoother at all for Hexa meshes. It doesn't know to keep the hanging nodes aligned. It is more for tetra prism meshes.
If you are going to smooth...
