Unit Cell with Periodic Boundary Conditions in ANSYS

Unit Cell with Periodic Boundary Conditions in ANSYS

(OP)
Hi All,

Im having an issue with periodic boundary conditions applied to a unit cell consisting of a fibre embedded in a matrix.

I am attempting to evaluate the shear modulus by applying a homogeneous shear strain, calculating the average stress over the face, and then dividing.

The issue is at the cell corners - there appear to be too many boundary conditions for ansys to handle (i.e. too many master / slave interactions).

I have attached a ppt explaining my boundary conditions in more detail.

Any help would be greatly appreciated!

Thanks
