Dear Yuxiang, Yes, indeed the co-dimension 2 case is not supported as of yet. However, I think that there is sufficient robustness in the current implementation of the Abaqus grid reader that it would be possible to implement this without too much difficulty. The three places that one would

Hi Jean-Paul, Thank you again for the fix and sorry to bother again. I wonder that, would you think it'd be easy to have spacedim = 3 and dim = 1 implemented? This would be very useful for beam elements (e.g. Timoshenko beams). I saw here that:

Dear Shawn, No, its fine. I see that the changes weren’t as drastic as I thought they’d be, so I think that the boundary ID assignment will work out of the box (I’d forgotten that someone else had already done much of the work necessary to support codim-1). I’ve made a patch to add this

Oh I see! Thank you for explaining. My guess would be that the ABAQUS equivalent is "node set". Please let me know if you'd like me to try that! Best, Shawn On Wed, Sep 19, 2018 at 10:00 PM Jean-Paul Pelteret wrote: > Hi Shawn, > > > Thank you for your help! I'd love to provide the mesh.

Hi Jean-Paul, Thank you for your help! I'd love to provide the mesh. Please let me know whether the attached one would work. For the boundary coloring - could you please elaborate on what that means? I wasn't aware that ABAQUS has such a coloring feature but it could be me not knowing this

Dear Shawn, The GridIn::read_abaqus() function is currently not equipped to deal with the codimension 1 case. I might be able to find some time to look at this in the next few days though. In addition to the mesh file that you’ve already given us, may you please construct and give us a fully

Dear all, Sorry for the beginner question. I am trying to load a 3D quad mesh (i.e. not all nodes are co-planar for one element) to implement a Mindlin–Reissner plate. I wonder, can GridIn class read such meshes? Upon reading the document, it seems like if the input element is quad then it is
