Hello, developers! I have some problems using DEM-DMP calculations:
- How can I get the coordinates and radii of all particles? And is MPI broadcast required to call DES_RADIUS and DES_POS_NEW of all particles in all processes? In fact the DES_RADIUS sizes printed by different processes do not match the actual number of particles, although the DES_RADIUS and DES_POS_NEW sizes are the same in different processes.
- I found that the max_pip and PIP in different processes in the DMP calculation are different, and only the PARTICLES of the root process is equal to the actual total number of particles in the fluidized bed, and the PARTICLES of the other processes are all 1? Is this normal?
- I also want to know the relationship between max_pip in each process and the actual total number of particles, and how the particle IDs in each process match the IDs in the total particles? That is, the particle ID in the process is 1-max_pip, and the total particle ID is 1-total PIP. How to determine the ID of the particle in the process among the total particles?
The information printed out by DMP is as follows:
write (*,*) 'max_pip', MAX_PIP, PIP, PARTICLES, 'my processor id', my_id, '---------------------------------------'
write (*,*) 'size(PINC)', size(PINC), 'DIMENSION_3', DIMENSION_3,'---------------------------------------'
write (*,*) 'SIZE(DES_RADIUS)', SIZE(DES_RADIUS), ‘SIZE(DES_POS_NEW):’, SIZE(DES_POS_NEW), 'SHAPE(DES_POS_NEW):', SHAPE(DES_POS_NEW)
!The output results of different processes are as follows
max_pip 1350 1350 1 my_id 3 ---------------------------------------
size(PINC) 3906 DIMENSION_3 3906 ---------------------------------------
SIZE(DES_RADIUS) 2048 SIZE(DES_POS_NEW): 6144 SHAPE(DES_POS_NEW): 2048 3
max_pip 1755 1755 1 my_id 2 ---------------------------------------
size(PINC) 3906 DIMENSION_3 3906 ---------------------------------------
SIZE(DES_RADIUS) 2048 SIZE(DES_POS_NEW): 6144 SHAPE(DES_POS_NEW): 2048 3
max_pip 1755 1755 1 my_id 1 ---------------------------------------
size(PINC) 3906 DIMENSION_3 3906 ---------------------------------------
SIZE(DES_RADIUS) 2048 SIZE(DES_POS_NEW): 6144 SHAPE(DES_POS_NEW): 2048 3
max_pip 1418 1418 4860 my_id 0 ---------------------------------------
size(PINC) 3906 DIMENSION_3 3906 ---------------------------------------
SIZE(DES_RADIUS) 2048 SIZE(DES_POS_NEW): 6144 SHAPE(DES_POS_NEW): 2048 3
Thank you！
