Thank you.. 
Kindly go through the description given below:
Problem description:
The table in the left side is the actual calculation that I’m doing.
The data in the right side is supporting my calculation.
The left side table values describe the performance of a coil which is fed by current (270,429,600,…) at different strokes(3.5mm,3mm,2.5mm,….) from Ansys simulation.
I need to estimate force value for any combination of current and stroke (say 280A & 3.4mm) which need to be extrapolated from the right side available data.
For that I have used the Mathcad program above which picks force value for any combination of Current and Stroke.
Coming to the Left side excel calculation, Kindly assume that Initially I know only the values highlighted in green.
The force in each step decides the stroke in the next step.
The column highlighted in Yellow ( current and stroke) in each step have to decide what will be the value of force.
Since it is not possible to manually enter the F(current,stroke) values in Mathcad for each step to check what will be the force and write it in the column highlighted in blue in left side table, I m thinking whether this can be automated like iteration process. Either by linking this Mathcad program in excel and make it run each time or reading the excel data in Mathcad and obtaining the required force values to fill the remaining steps in excel.
