Hi,

I want to specify the drag coefficients of particles in DDPM model. However, I want to do this based on the property of individual particle instead of the solid phase of the cell, as my particles have different sphericity.

I try to use DEFINE_DPM_DRAG to do this. But it has some problems when I click calculte: received a fatal signal (Segmentation fault). Of course, if I only use dpm model, the calculation could continue.

We could only use DEFINE_EXCHANGE_PROPERTY to change the drag coefficient?

Could you give me some suggestions? THank you very much.

Best wishes,
