I have used ParaView to visualize numerical results from Open Foam and I think it is a great source to post-process hydrodynamic numerical simulations. I am currently using SI3D, a finite difference hydrodynamic model from which I get a 3D output binary file with the solution to the velocity components, pressure, Temperature and turbulence properties for different time steps and organized in a xyz domain. This file is binary and I am looking to be able to create a file with a format that ParaView can read and interpret as a numerical simulation of water flow, and thus make use of this powerful tool to analyze the numerical simulation results. I am keen to use this numerical model as this model has been tested before in lakes and estuaries with great results.
I understand that ParaView reads the numerical results from OpenFoam. My question is, what would it be the best format for me to create using matlab/python so Paraview identifies it as the results from a fluid dynamics numerical simulation? The source code I am using is SI3D (not supported by ParaView) and it provides the results in columns for all the variables (x,z,y,u,v,w,T,nut). My goal is to created a file with an extension that Paraview will identify as CFD numerical simulation results and plot the results for each time step.
is this a more clear explanation of my goal? I apologize for not being so clear on my first message.
Thank you for all the help, I was indeed able to create a .vtk file that ParaView reads (for 1 time step). However, I am facing this issue with the visualization of the paraview interface once I load the velocity field. Do you know why this could be happening?
Thank you for all, I was able to get it work properly by just installing ParaView 5.0. Perhaps this is a more compatible version with my intel. Thank you for all the help, I am truly grateful. Your responses allowed me to achieve my goal.
After reading a thread of NaN values in a VTK legacy file I realized one can not use NaNs assigned from matlab to create the VTK file and open it in ParaView. Since this is not possible, I was wondering what should I replace the NaN value into so ParaView recognizes it as NaN value. Is it an option to replace the NaN into a blank space. I am afraid this configuration might loose the sequence of the data points with the data vector values.
