<div>Hello,</div>
<div><br>
</div>
<div>I have some arrays storing the values of the data and I want to write it as a vtk file, the data is unstructured <span>tetrahedrons</span></div>
<div><br>
</div>
<div>- Three arrays (<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;">X, Y, and Z) </span>storing the coordinates </div>
<div>- An array (data) storing scalar field </div>
<div>- An array (<span style="font-size: 12pt;">ptIds) storing cell connectivity </span></div>
<div><span style="font-size: 12pt;"><br>
</span></div>
<div>I'm trying to pass the scalar field to <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;">
vtkUnstructuredGrid but I get an error: </span> </div>
<div><br>
</div>
<div>error: no member named 'SetInputData' in</div>
<div> 'vtkUnstructuredGrid'</div>
<div><br>
</div>
<div>This is the code I'm using </div>
