I have successfully run a sensitivity analysis and parameter variation, and now have access to the automatically generated output files corresponding to each case.
Looking at the Reference Manual (p485-486) the following points gain my attention:
Note that the Min and Max project contain a collection of results from different parameter variations and do not form a consistent set of results for one particular set of parameters.
The Min and Max project may be used to evaluate the range of results that can be expected based on the parameter variations considered
I have opened the <projectname>_Max output file and am viewing the results.
Can someone clarify what point (1) actually means in the context of interpreting the results? I thought this <project>_max output simply reflects a calculation using max[param1] and max[param2] - even though this is not actually a combination I care about.
How can I usefully use these ParVar outputs to assess how one variable changes with variation in a parameter? I do not just want to view arbitrary combinations of results. Not sure if i'm missing something.
Do the other folders named 0 to 3 in the image have any utility here?
Thanks
Dear Max,
Projects 0 - 3 are the actually parameter variations, hence every of those projects represents a combination of parameters.
The Min and Max projects gather for every node and stress point the maximum value that occurs in projects 0 - 3 and put that together. So the Min and Max project show for every point the minimum and maximum value over all variations. It can very well be that a certain node gets the maximum displacement from variation 1 and the minimum displacement from variation 2 while the adjacent node gets the maximum displacement from variation 3 and the minimum from variation 2 while the maximum excess pore pressure comes from variation 6 etc....
This is what remark 1) in the manual indicates....
With kind regards,
Dennis Waterman
