I am simulating a three phase busbar disposition with magnetostatic module

the dimensions of the busbar are:

width 6mm

height 75mm

long 1000mm

separation among phase bars 7.12mm

current densities in t=0s

current density phase A=77.66A/mm^2

current density phase B=-38.83A/mm^2

current density phase C=-38.83A/mm^2

maximun lorentz force in t=0s

Phase A=-7524N

Phase B=6120N

PhaseC=1405N

current densities in t=3.333ms

current density phase A=38.83A/mm^2

current density phase B=38.83A/mm^2

current density phase C=-77.66A/mm^2

maximun lorentz force in t=3.333ms

Phase A=-1405N

Phase B=-6120N

PhaseC=7524N

results reported by article

maximun lorentz force:

Phase A=6578N appearing in t=0s

Phase B= 7051N appearing in t=3.333ms

Phase C=6578N appearing in t=3.333ms

The author in the article performed a time step simulation with f=50hz using Opera Software

I am performed a magnetostatic simulation and comparing the results by time instant using FEMM Software

in theory, the maximum shortcircuit forces are obtained in middle phase conductor (PhaseB), anybody can advice me about what is wrong in this simulation?

thanks a lot
