Unsteady flow CCM+
I am modelling the unsteady flow throught a racing car's airbox, which is running a presure inlet and mass flow at the outlet.

I have engine data which plots time against mass flow rate, but I dont know how to get CCM+ to communicate with the data/script file.

Any help will be mush appricated! Thanks

Re: Unsteady flow CCM+
load in an external table using the table tool (in the tools folder) then set your boundary specification to table and not constant

Re: Unsteady flow CCM+
Thanks, I am relatively new to this,

What file format should the table be? I just have two varibles, so would a .xy table be ok

Re: Unsteady flow CCM+
yup, two columns separated by a space should do

Re: Unsteady flow CCM+
thanks so much, but when i run the simulation an error appears stating "non-existant dataname in table"

the table is plotted (timestep pressure_at_timestep) and the "constant" under the pressure outlet to Table(time) has been changed etc.

Also, is it possible to run a pressure inlet in CCM+?
