Dear Al
Thanks for your help. I realised the option of the quadratic solution
but I was puzzled about the Find function, and was curious about a
possible solution. I appreciate your suggestion!
Thanks once again,
Tiny

You need to "Parameterize the solve block". That is, rather than type
"Find() ->" you need to define MyFunc(a):=Find(a) and then call MyFunc.
This is described poorly in the quick sheets, but allows a given find
block to be a function.
In your case, the equation is a simple quadratic, and I assume one root
is physically unrealistic. You COULD just write the quadratic eqn and
pick the right branch.
Once you have the find block as a function, you can put it in a
programming loop to iterate. I suspect there are other approaches that
will work as well, but this WILL get you to the end.

Subject: RE: [mathcad] about the function Find
Dear Mathcad users
I wonder whether someone can help me with the following (small) problem.
I am using the function Find for solving an equation in a Solve block
using the symbolic equal sign ("the arrow"), see accompanying file (I am
using Mathcad 11). I do not seem to be able to capture the solution of
the find function into a new parameter, in other words I have to fill in
the value manually. There must be a way to do this but I can't figure
out how.
As you will see it is an iterative calculation; it usually converges
after three iterations. there must also be a way to automate this.
However, the first mentioned problem is the most annoying one. I hope
that someone can help me out here. Thanks a lot in advance!
