[Fortran] How to open .hdf5 file extension

Click For Summary
SUMMARY

To open and process a .hdf5 file in Fortran, users must utilize the HDF5 Fortran API, which allows direct interaction with HDF5 files. The HDF5 library must be installed, and the Fortran program should include the appropriate header files. Users can read data using specific HDF5 functions such as H5Fopen and H5Dread. This process eliminates the need to convert the data to a .dat format using Python.

PREREQUISITES
  • Familiarity with Fortran programming
  • Understanding of HDF5 file structure
  • Installation of HDF5 library (version 1.10 or later)
  • Basic knowledge of compiling Fortran programs with external libraries
NEXT STEPS
  • Install the HDF5 library for Fortran (version 1.10 or later)
  • Learn HDF5 Fortran API functions such as H5Fopen and H5Dread
  • Explore examples of reading HDF5 files in Fortran
  • Research compiling Fortran programs with external libraries on Linux
USEFUL FOR

This discussion is beneficial for Fortran developers, data scientists working with HDF5 files, and anyone needing to process hierarchical data formats in their Fortran applications.

Hello, i am relatively new linux user so please be as thoroughly descriptive as you can.

i am starting a project and i have a file "file.hdf5" which contains velocity data i need to process in my fortran program. What do i have to do in order to use the data inside this file?

i normally use .dat extensions and i simply do:

open(unit=1,file="file1.dat",status="replace")

do i=1,N
read(1,*)...
enddo

In this case what procedure should i follow?? Is it possible to do it directly from fortran or i must extract them using python?? I need any libraries for this and if so how do i install and use them ( haven't used any libraries before).

if anyone has the courage to explain i would appreciate!
