I have imported this model from a CAD program. I am having difficulty meshing it. I would really love any suggestions as to how I can go about achieving the following :
1. The model is symmetric about the Y axis. That means the nodes on the left side and right side faces (as marked in the figure) need to match. How do I go about doing it?
2. Is it possible in Abaqus to create a Hex/ Hex-dominant, conforming mesh for this model? If so, could you name a few methods in which I can do it?
Thank you so much for all your time in answering my questions!
You can cut your geometry on the zy plane, mesh it and mirror the obtained mesh.
I hope this can help you.

Hello Franco,
Thank you, your suggestion helped. I cut the geometry in the YZ plane, and instead of mirroring the mesh, I mirrored the part and then merged the instances in Abaqus. Was able to obtain equal nodes!
I have, however a sub-question to the above model.
If I want to model the inner curved geometry using BEAM elements and the surrounding cube using SOLID elements, how do I tie the nodes between the beam and solid elements in Abaqus?
I want to reduce the cost of solid elements.
You can cut your geometry on the zy plane, mesh it and do the analysis with a symmetric FE model, which allows you to reduce solution time and also sounds more correct from a theoretical point of view
