I GOT BIG DIFFERENCE IN SIMULATION USING Q3D AND HFSS?

WHILE I TRY TO MAKE SIMULATION TO A VIA STRUCTURE USSING BOTH QUASI STATIC(3D) AND FULL WAVE(HFSS) AND TRY TO GET THE RAC,LAC.. FOR BOTH
I GET THE SAME CIRVES SHAPES BUT BIG DIFFERENT IN VALUES
FOR EXAMPLE AT CERTAIN F
R_Q3D=40 mohm RDC_HFSS=70 mohm
L_Q3D=50 PH L_HFSS=17 PH

ANY SUGGESTIONS?
NOTICE: I AM SURE DIMENSION < LAMDA /10 SO THE Q3D IS VALID
