writing in hdf5

[marciapearson@yahoo.com.br]

Hi everyone!

I am trying to save some hydrodynamic information in a hdf5 file in a program that is not Mohid GUI, but after this I will have to make Mohid GUI read this data. So, as reference I am looking how the Module HDF5 does it. I don't get the changes between the HDF5WriteDataR4_3D subroutines... I see that they save arrays with different dimensions (1D, 2D and 3D), but what does R4, R8 and I4 mean?

Best regards,

Márcia

Hi Marcia,

The diferences are due to type of 1D, 2D or 3D array.

R4 - single precision real type
R8 - double precision real type
I4 - integer type

Hope to have helped. Best regards,
Luis

Hi Luis!

Thank you for the answer. Now I have another question: what is the difference between Horizontal velocity Old and Horizontal velocity New? I found this in ModuleHydrodynamic in the subroutine that writes the FinalFile in binary format (subroutine Write_Final_Hydrodynamic_File).

Thanks in advance again!

Olá Marcia,

New is related with the current time step, and Old to the previous time step.
These matrices are need to continue the simulation from a previous run.

Cheers,
Luis
