Hi,

I have jEPlus1.5 running successfully on my PC and have run a Latin Hypercube Sample of 150 simulations from a jEPlus job with 12 Parameters which each had 5 alternative values (potentially 244,140,625 jobs). This fulfils one of my objectives exactly. Thank you for creating this tool and your help to date.

I also have another task I need to perform. I need to assess the relative impact of each of the 12 parameters with the values of all other parameters held at a nominal value. Eventually I want to extend this to assess the relative impact of over 500 hundred parameters, but first I need to prove a method.

If I arrange my parameters in a tree with each parameter described by a low, nominal and a high value I end up with potentially 3^12 = 531,441 jobs. However, I only really need to run 3 x 12 = 36 jobs. These jobs would be:

Jobs 1 to 3: parameter1 = {low, nominal, high}, parameter2 = {nominal), parameter3 = {nominal}, parameter4 = {nominal}, etc.

Jobs 4 to 6: parameter1 = {nominal}, parameter2 = {low, nominal, high}, parameter3 = {nominal}, parameter4 = {nominal}, etc

Jobs 7 to 9 : parameter1 = {nominal}, parameter2 = {nominal}, parameter3 = {low, nominal, high}, parameter4 = {nominal}, etc

etc

Can this be configured from the Parameter Tree field on the Project Tab? How?

This would be manageable with a small number of parameters but will become unwieldy when I expand my analysis to over 500. Is there a way of configuring jEPlus from an external file such as csv or txt? I.e. A way of telling jEPlus to only run specific simulations from the tree?

Thank you in advance.

Regards, David.
