mass flow unit change
I want to view massflow rate in the unit of kg/millisec in CFD-post. how can i do it? and
In pre i've given mass flow rate in kg/sec and i do a transient simulation for less than 1 second. now i want to know the total mass flow for the particular time period. |
Just Units...

Rate is rate, nomatter how long you calculate it. Just divide by 1000 and you end up with you kg/millisec. neewbie |
Re
how can i change the unit showing in post?
even through custom mode i can change to kg/sec, kg/hr and kg/min but i can't able to change into kg/millisec.. |
hi,
1.create an expression like mymf=Fluid.Mass Flow 2.create an Variable mymf which is the expression mymf AND here comes the trick 3.make a new variable which is a copy of mymf(variable) letīs say MassFlow then rightclick over MassFlow --> edit in Command Editor and add a field like kg ms^-1 at the field User Unit. I guess you could just do the second step (Frozen Copy of a Variable) since you probably already have something like Fluid.Mass Flow neewbie |

Pls show me the screenshot of 3rd step if possible because i've not seen any user unit line there...
Pls ref the attached pic. |

i donīt know what your expression mf is like. anyways.
but i actually discovered that cfx will change the units back to kg/s, so you will have to change to not showing the units in the legend and than insert a textbox telling the corresponding unit (e.g. [kg/ms]). for my way was working,... so im not sure why it isnīt the case for you. neewbie |
