how to increase the number of elements

Hi Satri,

If you're using the built-in cube geometry in EDEM, then it is not possible to change the number of elements. In this case, you have to create a cube geometry using an external CAD software where you can control the number of elements and then you can import that geometry into your EDEM deck.

I am creating a external CAD file should i import stl file or can i import a mesh file?

ok i imported the mesh so i have a square plate of 7000 micrometers side length. If i give the import unit as microns because i created the mesh in microns, I get a plate of 7 microns. If I give unit of millimeter when i import into edem it imports correctly. so why does such a thing happen?

Hi Satri,

Something must have happened when the geometry was exported or when it was imported in EDEM, but I'm glad you were able to import it correctly. When choosing the units, you can select CAD units and EDEM will try to infer the units from the CAD file.

ok what about the particle can we mesh the particle too?

Suppose i have a spherocylinder particle and want to increase the mesh points on it can it be done?

Hi Satri,

It is not possible to change the mesh size of the built-in spherocylinder. However, you can import any mesh with any mesh size you want and use it as a polyhedral particle in your simulation.

Suppose I make a spherocylinder particle externally and import it as a polyhedral particle with mesh?

Will it work

And will bond_3_5 api, particle replacement api and hertzmindlin gpu api work if I do it this way?

The bonding v3_5 API uses the getPhysicalRadius function, which is only available for multispheres and spherocylinders, so it will not work with polyhedral particles. I think the particle replacement API should work with polys, but I'm not 100% sure. Finally, the built-in hertz-mindlin model works fine with polys. If you are using the API version of the model, just make sure you're not using any multisphere and/or spherocylinder exclusive functions.
