Dear foamer
The etc/bashrc contains WM_PRECISION_OPTION that default is DP (double precision). I try to refine the mesh in near a plate to ensure mesh independence. Unfortunately, before reaching 2% relative error, the result shows perturbation. May it due to rounding variable? what about LDP, how many time it is bigger than DP? Thanks |

I don't think there is LDP, and I don't think whatever the issue you are facing at the moment is related to the floating-point representation.
