  We study $^{208}$Pb+$^{40,48}$Ca reactions at $E_{\rm beam}$ = 50, 100 AMeV
with DJBUU and SQMD transport codes. We compare the large primary fragments
from the two codes at the end of the simulation time. We observe that overall
the two models produce similar fragments. However, we see a noticeable
difference between DJBUU and SQMD at $E_{\rm beam}=100$ AMeV with the impact
parameter $b$ = 0 fm and discuss this difference in terms of the difference in
the equation of state adopted in the two models and the difference in stability
inherent to the BUU-type and QMD-type models.
