How to add modification term or factor to a model?

Please login with a confirmed email address before reporting spam

Hello everyone,

In pipeflow module, I would like to introduce some factor or additional term in the friction factor's expression. How can I implement that? I found it is impossible to invoke the internally defined friction factor experssion candidates such as Churchill's formula. I have to reimplement it by hand. It is easy to be affected by typo.

Is there any better idea?

Thanks

Di
