[gmx-users] mdrun error

[KRISHNA PRASAD GHANTA]

Hi gromacs user

I am simulating protein ionic liquid(IL) system, in my IL forcefield the
function type of dihedral parameter is 5. When I am running
gmx mdrun it appears the following error.


Program:     gmx mdrun, version 2018.1
Source file: src/gromacs/topology/topsort.cpp (line 139)

Fatal error:
Function type Fourier Dih. not implemented in ip_pert

For more information and tips for troubleshooting, please check the GROMACS
website at http://www.gromacs.org/Documentation/Errors
-------------------------------------------------------
application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0
[unset]: write_line error; fd=-1 buf=:cmd=abort exitcode=1
:
system msg for write_line failure : Bad file descriptor

After getting this error I have used function type 3 that also showed
Ryckaert-Bellemans dihedral error
Any suggestion will be appreciated to resolve this problem.
