[petsc-users] extract vector for a 2-D plane from a DM vector for a 3-D domain

[Roc Wang]

Hello,

    I have a DM and its vector for a structured 3-D domain and trying to extract the data for a 2-D plane.  I did some research on the manual and  noticed there is function named DMSlicedCreate(), however, it is for unstructured problem. Is there any ohter function to extract vector for a 2-D plane from DM vector for a 3-D domain directly? Thanks.
