ParaFOAM: Lagrangian Data

shock77 · February 18, 2021, 05:24

Hi,

I would like to know if there is an "easy" way to postprocess langrangian particle clouds in Paraview. I have the velocity fields of my particles and want to plot the velocity over a line.

I can export the data as csv and write a tool to make sth like that in particular, but I want to know if there is an easy method to do it.

Kind regards,
shock77

Thank you very much for your reply.

I am actually not interested in particle path tracking, but interested in plotting the particle velocities on a line at the certain time step. I have wirtten a matlab tool now to do so.

What also might be interesting, would be to interpolate the langrangian data onto a mesh.

-Can you share your matlab code, I am doing the same in excel but its taking a lot of time and effort. It would be great help if you can post it here.

-This is also an option but how to interpolate lanrangian data to eulerian data, is there any tool or utility available in openfoam or paraview?
