I'm trying to perform a QM/MM simulation in CP2K by taking the well equilibrated (seeing the tot_eng, pot_eng, temperature) configuration obtained from classical simulation in NAMD with charmm force field.

In QM/MM input file I use the simulation box lengths and its center of mass from the .xst file (NAMD) for a selected frame. The QM/MM input file is given below.

My QM system comprises of an organic molecule and 23 quantum water molecules in a QM box of 20x20x20.

While running the simulation, it showing very high temperature and then getting terminated with error

CP2K| Abnormal program termination, stopped by process number 2

rank 2 in job 1 cauvery_33033 caused collective abort of all ranks

exit status of rank 2: return code 1

I don't know why it is telling the geometry is wrong. Please suggest me something in this context.

The input file is attached with this question.
