Hello wentaogong08,
Using grep command for Linux or findstr for Windows can give you the answer, e.g. for Linux typing :
grep TURBULENCE */*cas |grep ' 3'
in the $HOMETEL/examples/telemac2d directory gives you:
2Dcoupling_algae/t2d_littoral.cas:TURBULENCE MODEL : 3
canalalgae2/t2d_canal_algae2.cas:TURBULENCE MODEL : 3
canalalgae/t2d_canal_algae.cas:TURBULENCE MODEL : 3
dragforce/t2d_dragforce.cas:TURBULENCE MODEL : 3
init/t2d_init.cas:TURBULENCE MODEL : 3
init/t2d_init_cin.cas:TURBULENCE MODEL : 3
init/t2d_init_cin_source_by_reg.cas:TURBULENCE MODEL : 3
riv_art/t2d_riv_art.cas:TURBULENCE MODEL : 3
Hope this helps,
Chi-Tuan
