I would like to create an UDF where I define a table with 2 columns.
time | mass flow rate
Lets say at the end there are 100 times and 100 corresponding values.
Between these values a linear interpolation would be nice.
Is this difficult to handle? I always find time-dependent functions but nothing with certain values.
Thanks a lot in advance.

I would simply read the values into a global 2-d array at the beginning of the run.
You'll need to write your own linear interpolation function, but if you're doing CFD it shouldn't be too hard
Then, you can call the interpolation in your define profile function (for mass rate), passing it the actual flow time and returning a double which represents the mass flow rate.
If you need more help, let us know!
