Using the DEM integrated in Star ccm+ the cylindrical packing has been generated.
Now I want to export the location of these settled cylindrical particles to re-create these in a CAD software.

The methodology to create a XYZ internal table and select appropriate scalar well with spherical geometries, I have tried it. The position represents the center of the sphere and then you can add the diameter to it.

But when you have cylindrical particles, the position of the center of the cylindrical particles is not sufficient to recreate the model in the CAD, you require the axis or the orientation of the cylinder as well i.e. you need the starting point and the end point of the cylinder.
I would really appreciate if anyone can tell me, which of the scalars in Star ccm represents this function (Axis or orientation) correctly for cylindrical particles. If anyone has tried it?

I am actually trying to use DEM to simulate efficiency of a filter. You know the radius and height, you also know parcel centroid, but you also have the orientation, for example is this picture, i,k normal is 0 and j is 1, thus I think you can work it out,

Thanks for the reply !!

I guess I have the centroid as well as the orientation of the cylinders, but they are not aligned to a particular axis (i,j or k), each axis has a values in orientation.
And if I have for example 1000 cylinders, each one would be having a different orientation.

I don't know if it is that straight forward.

I've sent you a message. Would you please help me about the re-creation of the spherical particles in the CAD software?

what is this mean?

Parcel Axis Orientation i contain i, j ,k
Parcel Axis Orientation j ,k also contain i, j, k


so, Parcel Axis Orientation have 9 variable? I am confused!
