PRECISION, LABEL
Specifies machine precision for solvers (currently valid only for PCG solvers).
MP ME ST PR PRN <> <> <> EM <> <> PP <>
Machine precision to use for solvers:
0 or double | — | Specifies double precision (default). |
1 or single | — | Specifies single precision. |
When the PCG solver is specified by the EQSLV command, this command can be used to specify single precision for the solver. By using single precision, about 30% less in-core memory is used by the PCG solver. However, using single precision can lead to unconvergence for the PCG solver when the problem is ill-conditioned. Double precision is the default and the recommended option for the PCG solvers. Single precision (LABEL = 1) is not supported in Distributed ANSYS.
