Hi everyone,<div><br></div><div>Is it possible to do second derivatives? What I mean by that is things like div[grad[u]] and grad[grad[u]]. I haven&#39;t tried this out yet, but we use these discretizations a lot for our research, and FEniC&#39;s inability to do this made us sad (although our more major qualms had to do with its inability to support quads).</div><div><br></div><div>Thanks,</div><div>Justin<br><br></div>
