Is possible to generate elements (SKR module) to use in FEAP or Abaqus for problems involving additional degrees of freedom?

I'm trying to generate an 3D element to establish the mechanical equilibrium of a problem involving coupling between displacements $\mathbf{u}$ and the field $\psi$)

Strong form of the BVP: coupled problem

  • $\begingroup$ Are you looking for elements with coupled physical fields, like displacement and temperature field? It is possible to generate (SKR) subroutines for such elements for different environments (FEAP, ABAQUS, etc) with recent versions of AceFEM (6.816). Use the the interactive panel by clicking "AceShare"->"Main Library"->"Select element"->...->"Generate element". $\endgroup$ – Pinti Sep 20 '17 at 8:04
  • $\begingroup$ @Pinti. That's exactly the physical coupling I was looking for: coupled temperature-displacements problems. Using the interactive panel for element generation I was able to generate an element for FEAP/Abaqus environment. However, the generation led to an element with 24 dof and 16 nodes (8 for displacements and 8 for temperature). I was hoping to obtain an element with 8 nodes and 32 dof. $\endgroup$ – João Pedro Ferreira Sep 21 '17 at 15:37
  • $\begingroup$ Are you sure that you chose correct topology and other settings? Maybe you could edit your question and add more details about what are you trying to achieve? $\endgroup$ – Pinti Sep 25 '17 at 7:42
  • $\begingroup$ This PhD thesis about coupled problems in AceGen could be useful for you. Unfortunately it is written in Slovenian language, but there are plenty of code snippets and examples inside. $\endgroup$ – Pinti Sep 25 '17 at 7:48

    $\begingroup$ @Pinti, The PhD thesis partially solved my problem. Unfortunately, the use of SKR AceGen module still bring some limitations, especially for the type of problems I've exposed. Thank you for your time. $\endgroup$ – João Pedro Ferreira Jan 25 '18 at 14:08
