Hi,
I am working on 3D periodic foundations. I need to get the phononic bandgap diagram for it. I have done the modelling part but while computing the study it is showing an error of inconsistent unidirectional constraints in solver. Can someone help me with how to resolve this error.It will be very helpful because my project in on hold due to this error.
Thank you!
Hemant

You get that problem when your mesh is not periodic.This problem arises when you are working with periodic bounary cnditions, specifically with 3-dimensional structure.

Make consistent mesh and the problem will be solved. Having identical mesh on periodic BC's is essential in this case.
