Task
Understand - how rotational DOF are integrated inside EDEM. For this: prepare simulation which could be compared with analytics.
For this:
- Prepare factory that creates particles
- Prepare contact model which describes the rule of interaction
- Prepare EDEM simulation
- Measure something and compare it to analytic
Who we are
- Степанов Алексей (responsible for contact model)
- Дзенушко Дайнис (responsible for factory and EDEM simylation)
Factory
We create 2 particles on a distance 0.1m and rotated at an angle of 5-15 () degrees;
These particles are of 2 types "small" and a "big" one; Big particle has identity matrix as rotation matrix; Small particle is rotated using rotation matrix
Particles's velocity and angular velocity equals to zero;
Y and Z coordinates are the same (0.5,0.5); Only X is different (0.45 for "big" and 0.55 for "small");
- For small particle:
double OrientAngle = pi/12; // angle between particles in Radians
orientation[0] = 1.0; // Rotating particle. X axis.
orientation[4] = cos(OrientAngle);
orientation[5] = -sin(OrientAngle);
orientation[7] = sin(OrientAngle);
orientation[8] = cos(OrientAngle);
Contact Model
Alexey will soon write about it...
