我正在尝试运行一段用f95编写的fortran代码。我已经在Ubuntu中使用gfortran对其进行了编译。
在代码中,有一个命令可以读取文本文件。当我运行它时,它给我以下错误:
Fortran runtime error: Cannot open file 'input_parameters.txt': Operation not supported
这是直到我们尝试读取文本文件为止的代码:
program LSmodel
implicit none !this is a fortran thing that means that all variables that start with i,j,k,l,m,n are integers.
real :: sec,ran,gasdev ! random generator variables
real :: x,y,z,u,v,w,ut,vt,wt,t,dt ! simulation variables
real :: wg ! seed parametes
real :: Um,sigma_u,sigma_v,sigma_w,uw ! wind statistics variables
real :: dvaru_dz,dvarv_dz,dvarw_dz,duw_dz ! wind statistics variables
real :: dissip_m,TL ! vector over the range of ustars
real :: zs,zg,zmax ! release height & boundaries
real :: Ainv,C0inv ! inverse parameters
real :: C0,A,b,au,av,aw,dt_on_TL ! LS model parameters
real :: dz_max,dt_max ! time step limit
real :: CT,beta ! Crossing Trajectories correction

我正在运行Ubuntu 18.04.2 LTS。
一个更新-尽管我不知道为什么,但我已经找到(我相信)此代码无法正常工作的原因。
该文件夹位于网络驱动器中,而不位于本地计算机上。将文件夹移到本地计算机后,我停止出现此错误。
