cefine

This is the official repository of the cefine program developed by the Grimme group in Bonn.

cefine is a commandline wrapper around the TURBOMOLE define program. The program is distributed as is!

Installing

To compile cefine from source install Intel Parallel Studio 17 or later.

>ifort -o cefine cefine.f90

Usage

Providing a clean folder with a tmole coord file, setting up a PW6B95-D3/def2-QZVP calculation can be done by calling:

> cefine -func pw6b95 -bas def2-QZVP -d3 -ri -grid m5 -scfconv 7

 Command line define V2.2, SG,HK 2006-18  August 2018 (-h for help)

cml-input: cefine -func pw6b95 -bas def2-QZVP -d3 -ri -grid m5 -scfconv 7           
 * RI-DFT(m5)-pw6b95/def2-QZVP * 
 define ended normally 
#atoms= 24
Number of MOs=     51, Electrons=    102.00, Symmetry: c1   
 HOMO/LUMO-SEPARATION :  0.153126

The total charge can be provided by the argument -chrg or by writing the charge into the file .CHRG. The number of unpaired electrons can be provided by the argument -uhf or by writing the number to the file .UHF. Both files, if available, are read automatically when calling cefine.

Infomation on all flags is provided by:
