[Pw_forum] Errors with structure optimization

[Oanh Nguyen]

Dear users!
I am optimising "vc_relax" for PdxTaSe2. I have a problem when I am running.
Not enough space allocated for radial FFT: try restarting with a larger
cell_factor.
Running with "relax" is ok

Here is my inputfile.
I already use lattice constant from experimental result.

How to the way to fix it?
