[ESPResSo-users] An error on espressomd

[陈敏]

After my compiling with default configuration(src/core/myconfig-default.hpp) on Ubuntu 18.04, I run a python script as follow:

——————————————————————————————————————————————————————

import espressomd

import object_in_fluid as oif

from espressomd import lb

import numpy as np

system = espressomd.System(box_l=[22.0, 14.0, 14.0])

system.time_step = 0.1

system.cell_system.skin = 0.2

# creating the template for RBCs

type = oif.OifCellType(nodes_file="input/rbc374nodes.dat", triangles_file="input/rbc374triangles.dat",

                        check_orientation=False, system=system, ks=0.02, kb=0.016, kal=0.02,

                        kag=0.9, kv=0.5, resize=[2.0, 2.0, 2.0])

# creating the RBCs

cell = oif.OifCell(cell_type=type, particle_type=0, origin=[5.0, 5.0, 3.0])

cell.output_vtk_pos_folded(file_name="output/sim1/cell_0.vtk")

# fluid

lbf = espressomd.lb.LBFluid(agrid=1, dens=1.0, visc=1.5, tau=system.time_step, fric=1.5, ext_force_density=[0.0002, 0.0, 0.0])

system.actors.add(lbf)

# main integration loop

maxCycle = 100

for i in range(1, maxCycle):

    system.integrator.run(steps=500)

    cell.output_vtk_pos_folded(file_name="output/sim1/cell_" + str(i) + ".vtk")

    print "time: ", str(i*system.time_step*500)

print "Simulation completed.»

Could anyone help me out?

Many thanks
