Hi everybody,

I am writing a small CFD code for a specific application. It is a hybrid continuum-atomistic simulation. A larger domain is solved with a CFD algorithm while some specific parts are solved with a molecular dynamics (MD) approach. The two domains are patched together in such a way that each part provides the boundary conditions for the other one. For visualization of the MD part, there is no problem, but for the CFD output I am not sure what file format to choose.
I was thinking at the PLOT3D file format, but it is not very well documented online.
Do you have any suggestion of a specific file format, well documented, readable by paraview and easy to implement that I can use for writing the CFD results?

Thanks in advance

Alessio

P.S: My data will be a set of velocity vectors and scalar field (pressure, temperature, concentrations) calculated at specific nodes (xyz) of the domain and the geometry will be not particularly complex (e.g. a sphere or a cube in a rectangular channel)

Greetings Alessio,

Google gave me these:

• CSV, XDMF and VTK: http://paraview.org/Wiki/ParaView/Data_formats
• VTK: http://people.sc.fsu.edu/~jburkardt/data/vtk/vtk.html
• HDF5 via XDMF: www.ci-ra.org/Documents/Seminaires/05-2009/ParaView.DataFormats_Types.pdf

Search expressions I used:

• vtk file format
• vtk file format example

Best regards,
Bruno
