Default Assign Particle Size in java for Polyhedral Partcles

Hello together,

I try to use a CSV file in which I exported location, orientation and particle size from a DEM simulation using Polyhedral Particles for a CFD simulation.

Unfortunately I have no idea how to assign the size of the particle in java when I am recreating the particles to use them for CFD. I use a template particle (an elongated dodecahedron) which is imported to my 3D-CAD Geometry. This template particle is transferred several times to parts (translated and rotated). I would like to assign the size from my CSV to the particle as well. This is how the coding looks like in java:

cadModel_0.createParts(new NeoObjectVector(new Object[]{body_0}));
SolidModelPart solidModelPart_0 =
((SolidModelPart) simulation_0.get(SimulationPartManager.class).getP art("Surface-Knit2"));
solidModelPart_0.setPresentationName("Particle Shape " + i);

simulation_0.get(SimulationPartManager.class).rota teParts(new NeoObjectVector(new Object[]{solidModelPart_0}),
new DoubleVector(new double[]{xRotationAxis, yRotationAxis, zRotationAxis}),
new NeoObjectVector(new Object[]{units_0, units_0, units_0}), rotationAngle, labCoordinateSystem_0);

simulation_0.get(SimulationPartManager.class).tran slateParts(new NeoObjectVector(new Object[]{solidModelPart_0}),
new DoubleVector(new double[]{x, y, z}),
new NeoObjectVector(new Object[]{units_0, units_0, units_0}), labCoordinateSystem_0);

Only the assignment of the particle size is missing. I saved the particle diameter as volume equivalent sphere in my CSV file.

Is there somebody who can help me out?

Thanks in advance.

you can set the size in the injector but you might need separate injectors for each size or change the size of one injector at each injection cycle
