<p style="margin-top:0;margin-bottom:0">Hello,</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">I am looking at the $GhostElements section of the MSH4 file format and there seems to be inconsistencies. According to the documentation:</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0"></p>
<pre class="example" style="line-height: 1.2em; font-size: 11.7325px; padding: 1em; border: 1px dashed rgb(47, 111, 171); background-color: rgb(243, 247, 255); white-space: pre-wrap; word-wrap: break-word;"><$GhostElements>
numGhostElement(int)
elementTag(int) partition(int) GhostCellOwner(int) GhostCellOwnerPartition(int) ...
<$EndGhostElements></pre>
<p></p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Here is my current understanding and what I would expect:</p>
<p style="margin-top:0;margin-bottom:0"></p>
<ul style="margin-bottom: 0px; margin-top: 0px;">
<li>'partition(int)' corresponds to the partition where the REAL cell is located</li><li>'GhostCellOwner(int) corresponds to the number of partitions in which element #elementTag appears as a GHOST cell</li><li>'GhostCellOwnerPartition(int)' corresponds to the list of partitions <span style="font-family: Calibri, Helvetica, sans-serif, Helvetica, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">in
which element #elementTag appears as a GHOST cell</span><br>
</li></ul>
<br>
<p></p>
<p style="margin-top:0;margin-bottom:0">However, when exporting the MSH4 format there seems to be a bug such that :</p>
<p style="margin-top:0;margin-bottom:0"></p>
<ul style="margin-bottom: 0px; margin-top: 0px;">
<li>'partition(int) corresponds to ONE of the partitions in which the element #elementTag appears as a GHOST cell</li><li>'GhostCellOwnerPartition(int)' corresponds to the partition in which the REAL cell is located</li></ul>
<p></p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">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 <span style="font-family: Calibri, Helvetica, sans-serif, Helvetica, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">'GhostCellOwnerPartition(int)'.</span></p>
<p style="margin-top:0;margin-bottom:0"><span style="font-family: Calibri, Helvetica, sans-serif, Helvetica, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;"><br>
</span></p>
<p style="margin-top:0;margin-bottom:0"><span style="font-family: Calibri, Helvetica, sans-serif, Helvetica, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">Therefore, it
seems that there has been a mix-up between '<span style="font-family: Calibri, Helvetica, sans-serif, Helvetica, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">partition'
and '<span style="font-family: Calibri, Helvetica, sans-serif, Helvetica, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">GhostCellOwnerPartition'.</span></span></span></p>

<p style="margin-top:0;margin-bottom:0">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 <span>296dd75f0b29090c28165df397cac4ff922832e5.</span></p>
