Hi,

I am running an explicit-dynamic analysis in abaqus with a subroutine for hyper-elastic material behavior. I used the plug-in to create PBC between two surfaces in my model. The plug-in does work well and creates the constraint equations for all the node pairs as intended. But when I submit the job, it gets stuck and the time-steps doesn't show up. Is there anything that I need to do with regards to the plug-in.

Thanks!

I am getting a KeyError while trying to pair my surfaces for Abaqus 2020.
All other aspects of the PBC are valid/true.
P632 is the part name and it is all one solid body.

Hi,
After start plugin I've got empty form (see attached). Please help. Thx.

Hi,

thanks for upload this periodic boundary condition plugin here. I am working on a 3D RVE and I want to apply pbc on it. I followed your implement instruction here:

Apply a periodic boundary condition on the two faces for the first direction without any exempted edges.
Apply a periodic boundary condition on the two faces for the second direction, and apply an exemption for the edges which are shared with the master surface for the first direction on the master and slave surfaces of the second direction (1 edge is exempted on each of the two faces).
Apply a periodic boundary condition on the two faces for the third direction, and apply an exemption for the edges which are shared with the master surface for the first direction or the second direction on the master and slave surfaces of the third direction (2 edges are exempted on each of the two faces).

After successfully add these constraint equations, I met a problem of applying uniaxal tensile loading. Abaqus saying the there is a DoF error at the loading node. Can you kindly suggest me how to add displacement loading in the RVE with periodic boundary condition？

When trying to run the plugin in Abaqus 6.14-3, the following error log is produced:

Hi,

the node pairing process ended with the following error if two surfaces created from a part with only orphaned mesh are used in the plug-in:

Traceback (most recent call last):

The same model with natively created mesh (same mesh) in Abaqus works with no problem.

thanks!
