I would think that it is the cylinder geometry that creates the problem. If I use pull = umbrellapull_geometry = distancepull_dim = N N Ypull_start = yespull_init1 = 0.0pull_ngroups = 1pull_group0 = DPPCpull_group1 = drugpull_rate1 = 0.0 The molecules stays in place. But pull_geometry=distance is what I would prefer due to the undulations. Changing pull_r0 and pull_r1 still makes the drug molecule move down towards the membrane...
