ACNI_v1_0 | CONVUS - LOW ENERGY | CPC 76(1993)80 |

Nature of problem:Problems in physics, chemistry, applied mathematics as well as in other fields, are often in need of an efficient 3-D convolution quadrature. | ||

Solution method:Algebraic manipulation and repeated use of Gaussian integration. | ||

Restrictions:Care must be taken to choose the integration cut-off properly. | ||

Running time:Same as for the low memory version (10.2 seconds). However if many integrals are to be calculated, the required time for each additional integral is only 1.5 seconds. |
