Reducing number of nodes on mesh

[sdantu2]

As the title implies, I need help of reducing the number of nodes below 1000 on a mesh as that is the maximum number of nodes that I can have on a mesh for simulation in Abaqus student edition. I have tried to use both -cl and -rcl commands to try to reduce the number of nodes, but I cannot get the node number to reduce below roughly 18000.

This is what I used for the tessellation: neper -T -n 100 -domain "cylinder(3,3)" -morpho "diameq:lognormal(0.150, 0.05), 1-sphericity:lognormal(0.145, 0.03) -o sample1

This is what I used for meshing: neper -M sample1.tess -elttype tet -cl (variable values) -> experimented with -rcl as well

In the meshing, I have used -cl and -rcl individually with variable values, however, I cannot get the number of nodes to what I require. I am not sure if there are limitations due to the way that I defined my tessellation or if I am just simply missing a command. Any help would be appreciated.

100 grains -> ~700 vertices, so it is almost hopeless already.

What I would advice you it to use "mapped meshing", using -rcl hex, so that you can control (and minimize) and the number of nodes in the model.

neper -T -n 100 -o n100
neper -M n100.tess -elt hex -cl 1/12

will give you 8281 nodes, and it will look like this:
