I keep receiving the same error messages while trying to mesh this model and I am not sure what to change in the mesh setting. I am doing a compression test on the model using explicit dynamic.

The model was created in SolidWorks and was imported in Ansys using x_t file format.

What version of ANSYS are you using? Is it the full version or a Student license? Do you have SpaceClaim?
If you have SpaceClaim, open the geometry there and use the buttons on the Repair tab to look for extra points, extra edges, missing faces. There are similar geometry checking capabilities in DesignModeler.
In Mechanical, on the Mesh branch, type in a much smaller element size.

I am using 2021 ANSYS and it is under my university license. I have SpaceClaim.

Okay, did my suggestions work?

[Ezzad]

I'm sorry but your suggestion did not work as I received even more error messages after repairing my model in SpaceClaim.

Open the geometry in SpaceClaim.
Put the structure in its own Component to separate it from the disks above and below.
Create planes to slice the structure up into smaller pieces. Open the Structure Component and use the Share button on the Workbench tab to create Shared Topology.
Now all the pieces of the structure will be meshed across the common faces. This will make it much easier for the Mesher to fill the simpler sliced volumes.
