Dear Colleagues,

 

I am using ABINIT to poerform the response-function calcultation on LaNi5. The q points are divided into several jdtsets, and the calculation are completed perfectly. However, I get stuck on running of MRGDDB(The two DDBs are obtained from two 'jdtset' seperately of the same input parameters).

 

Checking the two 'occ' sections(Please see the text followed), we found that the little difference(the value of 1E-14), i.e.,the electronic occupancy '0.19853482898721D+01' and '0.19853482898720D+01' in band No5 of the two DDBs,results in the failure of the running of MRGDDB. 

 

Would you please suggest that what parameters or variables can be set to control these errors in my input file for response-function calcultation.Any suggestion will be appreciated.

 

Thanks very much,

 

T Gam
