I am senior student

I tried to simulate plant of biodiesel but I have some problems with liquid liquid extractor

The message is warning " Fetal errors - zero in diagonal in a column matrix. There may be no solution

with the current specs."

How can I solve problem?

Thank you to reply me

I am sorry, but your question is about as badly stated as the Hysys error messages. The answer to your question how you can solve the problem is to supply us with all the necessary data, preferably your simulation file. Show us how you modeled the extractor, what the feed compositions are, the flow rates, pressure, temperatures, etc. Then you might be able to get a sensible answer - but you may find the answer yourself beforehand.
Asking the right question brings you (at least) halfway to the answer.
