error about fix heat command

Dear all,

I am trying to use ‘fix heat’ to conduct the evaporation of droplets, which add or reduce energy to a region has specified region for every n timesteps. And I used the new version of fix heat without ‘region’ option. When I run my input file,I got this error ’ Fix heat kinetic energy went negative’. The following is the input files.

Thanks.
