You can do the following:<br>
<br>
1. start with original surface (original triangles), with N nodes<br>
<br>
2. extrude by a certain distance: you get a new surface (new triangles)<br>
<br>
3. the extrusion simply adds corresponding nodes for each original node, so a node with id k has a corresponding node with id N+k.<br>
<br>
4. connect triangle i in original triangles with triangle i in new triangles. Make a prism for each triangle.<br>
<br>
5. convert all prisms to tetrahedra using "triangulate"<br>
<br>
<br>
Most of the code necessary for this can be found here (steps 1-4, 5 is already in paraview):<br>

I have a 2D Triangulated mesh that a user wants extruded into a 3D Shape for use in simulation work.<br>
<br>
I tried using the "Linear Extrusion" filter, but that only gets the outer edges. What I really need to do is extrude the triangles into 3D Triangulate Prisms (5-sided solids, 2 triangles & 3 quads). Is there any way to do this?<br>
<br>
I tried doing:<br>
Dataset<br>
|- Extract Surface - Linear Extrusion<br>
|- Extract Edges - Linear Extrusion<br>
Append both Together - Clean<br>
<br>
That's close, but I have a collection of 2D Primitives, and lose all the interior volume.<br>
