Divyaprakash is on a distinguished road
I have a set of points that represent a structure whose deformations are solved for at every time step. I am storing those points as follows.


Code:
std::vector<double> pposx, pposy, pposz;
How can I write them down at everytime step so that it could be read by paraFoam and be shown above the contour plots?

Note that "paraFoam" is a shell script, not a program. If you wish to visualize x/y/z values in paraview, you'll need to see what type of import possibilities are available. Either use your values to generate a CSV file and import that, or generate a VTK file yourself. The legacy VTK format is dead easy, but you might do okay with OBJ format too. Take a look at the coordSetWriters in OpenFOAM for inspiration.
