Hi, everyone.
I wanna calculate the total liquid film mass on the cylinder wall(liner) boundary in IC engine by using pro-Star's postprocessing utility(data loaded from *.ccmt file). The commands I used as follows: ---------------------------------------------------------------- bset,newset,region,11 ! boundary region 11->stands for liner cset,newset,bset operate,getw,lfm_1,1 !put area average liquid film mass in register 1(kg/m^2) operate,getw,area,2 !put (wall)area in register 2,the unit of area ( mm^2) operate,multi,1,2,3 !put the product of register1*register2 to register 3 operate,smulti,1.0e-6,3,4 !put the product of 1.0e-6*register3 to register 4 (kg) summarise,cset ---------------------------------------------------------------- but the last command cannot get the right results. Can anyone help me? thanks! |

This may work better:
bset,newset,region,11 ! boundary region 11->stands for liner operate,getw,lfm_1,1 vset news bset cset news vset all cset subs shell !put area average liquid film mass in register 1(kg/m^2) operate,getw,area,2 !put (wall)area in register 2,the unit of area ( mm^2) operate,multi,1,2,3 !put the product of register1*register2 to register 3 operate,smulti,1.0e-6,3,4 !put the product of 1.0e-6*register3 to register 4 (kg) summarise,cset |
