EDEM生成颗粒后，根据颗粒的位置、ID号，可以在edem中显示颗粒团外貌并提取颗粒团中颗粒数量的C++代码

以下是一个简单的C++代码片段，用于在EDEM中显示颗粒团外貌并提取颗粒团中颗粒数量：

#include <edobject.h>
#include <edem.h>
#include <edem_geometry.h>

int main(int argc, char* argv[]) {
    EDEM_INIT();

    // Load the simulation file
    const char* simFile = "simulation_file.sim";
    EDEM_RestartLoad(simFile);

    // Get a pointer to the particle group
    EdParticles* particles = EDEM_GetParticles();

    // Get the particle group ID and number of particles
    int groupId = particles->GetId();
    int numParticles = particles->GetSize();

    // Create a geometry object for the particle group
    EdGeometryObject* geometry = new EdGeometryObject(groupId);

    // Set the visualization style for the geometry object
    geometry->SetStyle(EGS_STYLE_SPHERES);

    // Set the radius of the spheres to be proportional to the particle size
    geometry->SetSizeType(EGS_SIZE_PROPORTIONAL);

    // Set the maximum radius of the spheres
    geometry->SetMaxSize(0.01);

    // Set the position of the geometry object to the center of the particle group
    geometry->SetPosition(particles->GetCenterOfMass());

    // Add the geometry object to the simulation
    EDEM_AddObject(geometry);

    // Print the number of particles in the particle group
    printf("Number of particles in group %d: %d\n", groupId, numParticles);

    EDEM_Exit();
    return 0;
}

该代码使用EDEM API中的EdParticles和EdGeometryObject类来获取颗粒团的位置和ID，并将颗粒团外观显示为球体。此外，该代码还提取了颗粒团中颗粒的数量并将其打印到控制台中。注意，这只是一个简单的示例，您可以根据需要自定义代码来满足您的具体需求。
