Hello,
I am looking at the $GhostElements section of the MSH4 file format and there seems to be inconsistencies. According to the documentation: <$GhostElements> numGhostElement(int) elementTag(int) partition(int) GhostCellOwner(int) GhostCellOwnerPartition(int) ... <$EndGhostElements> Here is my current understanding and what I would expect: * 'partition(int)' corresponds to the partition where the REAL cell is located * 'GhostCellOwner(int) corresponds to the number of partitions in which element #elementTag appears as a GHOST cell * 'GhostCellOwnerPartition(int)' corresponds to the list of partitions in which element #elementTag appears as a GHOST cell However, when exporting the MSH4 format there seems to be a bug such that : * 'partition(int) corresponds to ONE of the partitions in which the element #elementTag appears as a GHOST cell * 'GhostCellOwnerPartition(int)' corresponds to the partition in which the REAL cell is located As a result, if element #elementTag appears as a GHOST cell in multiple partitions, the current implementation will have the REAL cell partition number repeated multiple times in the 'GhostCellOwnerPartition(int)'. Therefore, it seems that there has been a mix-up between 'partition' and 'GhostCellOwnerPartition'. I am exporting a partitioned mesh in the MSH4 format using the latest stable binary (4.0.0, August 22 2018) and have tried the latest development build 296dd75f0b29090c28165df397cac4ff922832e5. Thank you for time. Best Regards, Doug
