Dear all,

As is well known in electron-phonon calculations, one has to do a self 
consistent (scf) calculation over a dense electronic grid followed by an scf 
calculation on a coarse grid.
The electron phonon calculation is usually performed after calculation the 
vibrational frequencies for each point.

My question is : If we increase the dense grid, Is it possible (Is there a way 
in QE) to compute the el-ph coefficients without recomputing the dynamical 
files (vibrational frequencies), which actually depend on the coarse grid.  
This would save a lot of time.

Thanks in advance
