Problem in Abaqus: I have 18 parts. Uploaded one of them and it was essentially 2M nodes!

I am remeshing and decimating in blender then converting to STEP in freecad

Is there a way I can force Tet meshing to follow some kind of pattern?

I have this holed unit cube which is partitioned in 8 regions and the 2 regions in which the hole is are identical.

When meshing them with Tets I am getting an extra internal node on one of them but I would like for both of them to be meshed similarly.

Is it possible to force abaqus mesher to at least match the same number of nodes and Tets on both regions?

Quasi Static Explicit Analysis Element Type

Hi everyone,
I am currently carrying a quasistatic explicit analysis, in ABAQUS where hyperelastic material properties plasticity and multiple instance contacts exist, Since the day I started FEA I have always used C3D8's but PEEQ values never converge no matter how I refine the mesh, I looked at everything contact definitions, mass scaling etc., I am suspecting something related to element type. What should I do?
Any help would be appreciated.

Unable to define the DC3D5 element

The DC3D5 element was clearly displayed during setup, but I can't define it. I'm using ABAQUS 2022.

My simmulation is not running due to excesive number of elements

HI, my simulations usually have around 240.000 elements.

I am running a model that is almost the same and suddenly I have 10 times the same amount of elements (i import the meshes and havent changed any parameter).

Is there anything someone else could have modified that could affect this?

I have also noticed that the CPU usage is almost none since it doesnt look like its trying to compute anything. Is there anything that could affect this?

I have two simulations left for my master thesis and suddenly they are not working.

Thanks in advance

SOLVED
TLTR: When creating the volume mesh, I had accidentally forced the element size to be 1 mm, creating objects with 3 million elements instead of 300.000
