Dear all, Once again I am writing regarding the D3Q code. When I run the d3q.x executable to compute the number of triplets on which the calculation of mat3R will be performed, I get: Looking for irreducible triplets out of 16 possibilities: 1: ( 0.0000 0.0000 0.0000 ) ( 0.0000 0.0000 0.0000 ) ( 0.0000 0.0000 0.0000 ) -->_Q1.0_0_0_Q2.0_0_0_Q3.0_0_0 2: ( 0.0000 0.0000 0.0000 ) ( 0.0000 -0.4999 -0.0075 ) ( -0.0000 0.4999 0.0075 ) -->_Q1.0_0_0_Q2.0_-1o2_0_Q3.0_1o2_0 3: ( 0.0000 0.0000 0.0000 ) ( -0.4999 0.0000 0.0168 ) ( 0.4999 -0.0000 -0.0168 ) -->_Q1.0_0_0_Q2.-1o2_0_0_Q3.1o2_0_0 4: ( 0.0000 0.0000 0.0000 ) ( -0.4999 -0.4999 0.0093 ) ( 0.4999 0.4999 -0.0093 ) -->_Q1.0_0_0_Q2.-1o2_-1o2_0_Q3.1o2_1o2_0 5: ( 0.0000 -0.4999 -0.0075 ) ( -0.4999 0.0000 0.0168 ) ( 0.4999 0.4999 -0.0093 ) -->_Q1.0_-1o2_0_Q2.-1o2_0_0_Q3.1o2_1o2_0 IRREDUCIBLE NUMBER OF TRIPLETS TO COMPUTE: 5 Setting up GGA 2nd derivative =================================================== = Starting D3 calculation = =================================================== = triplet 1 ( 1 of 5, 0% done) = =================================================== = q1 = ( 0.000000 0.000000 0.000000 ) = = q2 = ( 0.000000 0.000000 0.000000 ) = = q3 = ( 0.000000 0.000000 0.000000 ) = =================================================== . . . . .

This is most probably a memory issue. The grid I am using to do these calculations is the smallest for the case system I am using. Is there a way to circumvent this problem? Does the code print how much memory is needed? I could not find this information Regards |
