According to cp2k documentation
https://manual.cp2k.org/trunk/CP2K_INPUT/FORCE_EVAL/SUBSYS/KIND.html#POTENTIAL it
is possible to set POTENTIAL variable value as ECP, in order to use
Effective core potential. I've converted basis set
from http://www.tc.uni-koeln.de/PP/clickpse.en.html according to CP2K
documentation. The section KIND in my input file is:
* &KIND VBASIS_SET STOLL-PBEPOTENTIAL ECP&POTENTIALV nelec 10V ul2

The basis set in new file is:

CP2K starts normally but exit with error message:
*CPASSERT failed qs_mo_types.F:295*
By checking source code I have error here:
*CPASSERT(nmo >= nomo)*
Could someone kindly give a working example for force calculations with ECP
potential.
Many thx in advance,
Eugene
