Hi, everyone

I am building DEM-CFD model with MFIX software. In DEM model, there are two selection to define the number of particles. One is use the present code to automatically and randomly generate it, the other one is to specify the number of particles, such as 20,000 particle in a fluidbed. From MFIX, there is a fortran code which tells how to specify the number of particles, but i have no idea that how to use them to generate a .dat file.
I put attachment down here, kindly have a look. The .f file is the fortran code for specifying the number of particles, and in this code, 20.000 particles are defined.
Note: the particle_input.doc is not the .dat file due to it is invalid file to upload, but i list the part of contents in this .doc file. I need .dat file to define the number of particles.
I need you guys to help me how to generate the .dat file on linux by using the fortran code.
Thank you very much.
best regards
