Default extracting velocity and mesh data for a very big file without GUI

shashanktiwari619 is on a distinguished road
I am working on a very big size mesh (approx. 20GB polyMesh folder). The use the icoFoam solver to run my simulations on HPC in parallel. However, I am unable to post-process using a GUI either on a local machine while I don't have the rights to use a GUI on HPC. I just want to extract the mesh details and the corresponding three dimensional velocities to be extracted in a csv or any txt format. Is there any option in OF 3.0.1 to do so.
