Hi colen212,
It is good to hear that you are developing a plug flow model.
There are so many aspects of developing a model that I am curious as to what aspects you are looking at. This can get even into the complexities of colloids. I am curious as to the limits that you want on your program.
For example, I know of approximately 8 different methods of measuring viscosity. If you were to have viscosity as one of your parameters, you will need to spend much time on determining what you are looking at calculating.
In my personal opinion, gProms looks like a nice program, however, I have found that creating my own programs provides a little more options for me.
Could you help me out by describing more of the intent of your model, and some of the previous work that you have completed so that I can understand which area you would like help with?
I wish you the best,
Eugene
