<p>Dear all,</p>
<p><br>
</p>
<p>I need to use <span style="font-family: "Times New Roman", Times, serif, Times, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">Q3 tensor product Hermite element in 2D
(point value, gradient, and mixed derivative at 4 vertices in a cell as unknowns).</span></p>
<p>Is it available <span style="font-family: "Times New Roman", Times, serif, Times, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">in PETSc FEM module </span><span style="font-family: "Times New Roman", Times, serif, Times, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">now?
I found that</span> only Lagrange element is available.</p>
<p>If not, what is the correct path to implement Q3 tensor product Hermite element?</p>
<p>I think I should create my own petscspace and petscdualspace?</p>
<p>Or is there any package that has already provided this?</p>
<p><br>
</p>
<p>Thanks for any suggestions!</p>
