How to print the mesh details in a file after topology optimization

Hello,

I need to export the no of elements present after topology optimisation or the optimised surface area of the geometry. I can export it as a CAD file and find the area and so on...

But I would like to print them into a file, maybe a .txt file so that I can all for these values in a code that I am developing. 

Kindly let me know if there is a solution to this or should I obtain the information manually?

Thanks,
