It just has not been a priority to add support for partial assembly on triangles/tets but we definitely want to add that.
Depending on what integrator you need, you may be able to use partial assembly on triangles/tets using one of the libCEED backends. @YohannDudouit, can clarify which integrators can use the libCEED backend with simplices. The libCEED library is available here: https://github.com/CEED/libCEED.

Hi @sungho91 , mfem does not support partial assembly for simplex elements.

Hi @artv3,
I understand. Why doesn't MFEM support it? Is it due to technical issues or is it fundamentally impossible?

Hi @sungho91,
Which integrators are you trying to use?
from mfem.
@v-dobrev Thanks for your information. Yes, indeed, many third-party meshers generate triangles/tets, so enabling p-assembly for those elements is super desirable. I'll take a look at libCEED.
@YohannDudouit, my code is based on Laghos
. So, it uses mass integrators for H1 and L2 spaces, respectively. Also, it uses a force integrator.
from mfem.
@sungho91 The Mass integrator is supported for both H1 and L2, so using the libCEED backend should work there. However, I'm not too familiar with the force integrator, and this would probably need to be implemented using libCEED, I can assist you in doing so if you're interested.
