Title: Min/Max Accretion
Post by: wbsonic on September 11, 2017, 04:08:23 PM

I've been working on my accretion inputs for SLAMM, and was wondering how the Min/Max accretion rate parameters function within the model.

I developed some accretion curves through MEM. Do the Min/Max parameters set a cap on the rates these curves can reach?
Or do they adjust the curves to reach these set min/maxes?

To understand these curves and parameters, please see the spreadsheet:


Which is installed along with SLAMM. 

You will see that the equations describe a third order polynomial which then can be scaled to the min and max accretion values.  That allows you to play games keeping the shape of the feedback curve intact but increasing or decreasing the minimum and maximum accretion values as part of a sensitivity or uncertainty analysis.

Let me know if you can't find the spreadsheet or have additional questions.
