I am simulating a system with fene bond potential , although it gives me the data after the specified time step, but during the run process it has a lot of warning messages “fene bond too long”. In order to verify this problem I checked chain example existed in lammps documents/bench/in.chain & data.chain and it had the same error messages, now I am wondering is that a problem or not and if it is what should I do to remove this error messages.
actually I changed a lot of variables in fene bond coefficients and even other parameters, but none of them helped.
please help me!!!
