Please see the atteched apex file, which was made in Grizzly. I can't merge the nodes between the different parts. I make a 2.5D mesh bodies on parts, and unable to merge the common faces nodes. What is the best method to mesh all the geometry and the nodes to be connected?
You can't merge nodes between different Parts in Apex. The node merge tool is primarily intended for merging nodes on orphan meshes (i.e. meshes imported from a Nastran bdf), and in your model it won't work even if you put all the solids into the same Part, because the nodes belong to different mesh bodies.
For a solid mesh, one option is to glue your meshes together. However the better option is probably to create the model as a single partitioned solid. This will mean you can still mesh the cells individually, with individual mesh seeds if necessary, but the final mesh will be congruent.
If you can upgrade to the Harris Hawk release of Apex, you can boolean together your existing solids while retaining them as cells within the new solid:
Did you mean to do this way as in the attachment? Actually I have only access to Grizzly.
My problem is that I don't get different geometric properties associated to different parts of the mesh if I export in BDF, then loading it into Marc!? Is there a workaround in Apex to have different property groups in the mesh?
Yes, exactly like that. Unfortunately in Grizzly there's no way to have different properties on cells in the same solid (Harris Hawk is able to do this). I guess you would have to do that in Mentat...
I have downloaded Harris Hawk and played with the method described above, namely with the merging parts together as cells. But exporting to "bdf" and importing in Marc doesn't separate the cells mesh in different geometric properties. What else should be done, in order to get the different part/cell mesh ordered to different geometric properties?
I forgot to mention that I am trying to import into Marc 2017.
