sensitive analysis and arc length control in Plaxis 2D

Above with that above, why senstive analysis only shows criterion 1 (provided safety analysis in criterion 2) and sensiScore based on what criterion?

after doing parameteric analysis how to find which is worst what is meant by mini and max?

Thanks

Any reply please?

Please tell the answer for this , thanks

In arc length control, how the arc is defined?

I have 2 more question here as the max and min results from the parametric analysis provided the max and min results in the analysis based on the parameters which will be in a different combinations. My questions are 

1. If we provided 2 criterions lets say the vertical displacement on one node and FOS (strength reduction factor), here which value is considered as max and min as both may not coincide? 

2. In one analysis i provided 2 criterion as shown below.

and did parameter variation analysis as shown below.

when i see the failure case the failure line extended from 1 to 2nd layers of the soil 

when i checked the FOS for the max and min output from the parametric analysis results the values are shown below

but when i checked the soil parameters of the two layers in the two analysis the same values as shown below.

Layer 01 (not include in the par analysis but i showed here), (order max and min)

Layer 02 (order max and min)

Why is like that?

Hi,

0) On arc-length control, the arc is a second order parabolic determined by the step size.

1) If different criteria are used for different phases, then the Min-Max values per phase are based on the criteria of that phase.

2) The Min - Max projects are about the Minimum and Maximum results. Since they're obtained from different parameter combinations, the soil parameters in the Min-Maxi projects have no value and should not be considered.

With kind regards,

Thanks for the answer 2) so  in max and min, the input doesn't show the soil parameter changes?

Hello Nitha,

No, you would not see it as these are done in the backend. 

Thanks
