Meshing help, dragging created elements v12.0
Altair EmployeeHello,
I have been up all night trying to figure out an issue with no luck. Image 1 shows the mesh that I wish to solid map. This mesh was created using automesh for the outer rings and edit element -> create for the two inner rings (shown better in image2). The issue I am having is when I choose to use multi-solid, the inner two meshes aren't recognized and a new mesh is created over the one I build manually (image3 clearly shows both meshes, the program is acting like it doesn't know the original is there). When I attempt to reject this mesh it tells me that there is 'nothing to reject', but then when I go to make a new mesh it says 'reject previous mesh'.
Image4 shows the full geometry I am working with and image5 shows the section I am mentioning now.
A Solid Map -> Line Drag does work, but this method does not line up with the other meshes when the rest of the component is solid mapped and cannot be equivalenced because the distance is too great and causes element collapse.
It seems to me there should be an easy way for the program to do this, but I'm starting to see a trend in the software not being able to handle intricate meshes in a very efficient way.
I have provided my file for anyone interested in looking at it. (https://drive.google.com/file/d/0BxFH4UMMBHuXZ3VEY0RmY0xpWTg/view?usp=sharing)
Thank you,

You may have to use Geom > node edit > associate and then try with multi solids,
You can use general > elements to drag > elements to match
We have a lot of material - videos, tutorials, hints etc here - http://training.altairuniversity.com/modeling/meshing-2/3d/hexa-meshing/

Trying to avoid jumping the gun but I think not knowing the associate command has been my problem! That is a very powerful and useful tool. I will post back when I finish this mesh, but so far everything is looking great!
Thank you!

This method worked great for half my model, but when I try and mesh the other have it say 'no valid mappable left' but all of the remaining solids are still mappable. I have attached an image to show the issue. Very odd

I simply used a reflect command and equivalenced these nodes to finish it. Still interested in an answer as to why these were considered not valid mappable regions.

When your model is symmetrical, you not need to make all mesh, just a half. That's the 1st rule for meshing work.
