  用paycharm运行官网的代码，运行的是官网的案例：“c118296f-inverse-design-of-waveguide-crossing“”
  paycharm报错显示：raise UserWarning('FDTD simulation did not complete successfully: status {0}'.format(simulation_status))
  UserWarning: FDTD simulation did not complete successfully: status 0.0
  查看工作日志，有以下错误：Error GPU simulation cannot run without FDTD property 'express mode'，但是不知道怎么解决，运行的是官网的案例：“c118296f-inverse-design-of-waveguide-crossing“”
  详情问该怎么解决呢

  个人经验，pycharnm运行官网案例经常莫名其妙出错，建议用FDTD自带的 script editor运行脚本再试试

  首先，The FDTD GPU solver can only run 3D FDTD simulations.
  
  另外请确定express mode是否勾选，或者直接将改成CPU
