[CP2K:7159] Error in qs_dispersion_nonloc when increasing cutoff to 2000 Ryd

[hut... at chem.uzh.ch]

Hi

this is the stop you input triggers:

    !! Check to make sure that the kernel table we have is capable of dealing with this
    !! value of k.  If k is larger than Nr_points*2*pi/r_max then we can't perform the 
    !! interpolation.  In that case, a kernel file should be generated with a larger number
    !! of radial points.
    !! -------------------------------------------------------------------------------------
    CPASSERT(k < Nr_points*dk)

You now have two possibilities:
1) Generate your own kernel file with a higher maximal cutoff, see the Quantum-Espresso
   software for a program that can do that and for further instructions
2) Set a lower cutoff for the vdW functional only by using the keyword
   CP2K_INPUT / FORCE_EVAL / DFT / XC / VDW_POTENTIAL / NON_LOCAL / CUTOFF

regards

Hi,
I am trying to run a water structure using the aug-TZV2P basis set and a PW cutoff of 2,000 Ryd. I am using the mGGA B97M-V (through libxc) and the RVV10 for non-local correlations. I've been able to run this calculation for 600 and 1000 Ryds, but not for 2000. I get the following error:
***************************************************************************** *** 11:08:55 ERRORL2 in qs_dispersion_nonloc:interpolate_kernel processor *** *** 0  :: err=-300 condition FAILED at line 1260                          *** *****************************************************************************
I am not sure whether I should adjust any of the parameters in the input file because of the large cutoff. Any help would be highly appreciated. I have attached a tar file with the inputs and outputs.
Best,Luis
