Q2 Measurement of Aspect Ratio along principal
directionsMeasurements of Aspect Ratio were performed using Visit
visualization software
2a) 1 along all directions, as expected
2b) Mechanics solver appears to be working as expected, but
concentration field does not change accordingly (ratio still very
close to 1 for all axis
2c) Similar to 2b, the mechanics solver appears to be working as
expected, but the concentration field is again slow to change axis
ratio essentially unchanged from initial conditions
