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

load in an external table using the table tool (in the tools folder) then set your boundary specification to table and not constant

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

yup, two columns separated by a space should do

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+?

Thanks
