Create Envelope of Results

Identify the most significant result out of all selected analyses.

Before you begin, you must have one or more structural linear or multi-loadcase analysis results in the design study.

Envelope can be either max, min, or extreme. Envelope is mathemetically represented by the following equation for each point:

R s   =   min/max/extreme   c 1 R 1 ,   c 2 R 2 ,   …   c i R i MathType@MTEF@5@5@+= feaahqart1ev3aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr 4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq=Jc9 vqaqpepm0xbba9pwe9Q8fs0=yqaqpepae9pg0FirpepeKkFr0xfr=x fr=xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaWaaiWaaeaaca WGsbWaaSbaaSqaaiaadohaaeqaaaGccaGL7bGaayzFaaGaaGPaVlab g2da9iaaykW7daqadaqaaiaab2gacaqGPbGaaeOBaiaab+cacaqGTb GaaeyyaiaabIhacaqGVaGaaeyzaiaabIhacaqG0bGaaeOCaiaabwga caqGTbGaaeyzaaGaayjkaiaawMcaaiaaykW7daGadaqaaiaadogada WgaaWcbaGaaGymaaqabaGcdaGadaqaaiaadkfadaWgaaWcbaGaaGym aaqabaaakiaawUhacaGL9baacaGGSaGaaGPaVlaadogadaWgaaWcba GaaGOmaaqabaGcdaGadaqaaiaadkfadaWgaaWcbaGaaGOmaaqabaaa kiaawUhacaGL9baacaGGSaGaaGPaVlablAciljaaykW7caWGJbWaaS baaSqaaiaadMgaaeqaaOWaaiWaaeaacaWGsbWaaSbaaSqaaiaadMga aeqaaaGccaGL7bGaayzFaaaacaGL7bGaayzFaaaaaa@6A1A@

Scale factor.
min
Finds the minimum value among all the selected analyses weighted by appropriate scale factors.
max
Finds the maximum value among all the selected analyses weighted by appropriate scale factors.
extreme
Finds absolute maximum value among all the selected analyses weighted by appropriate scale factors. The sign of the number is not changed during result display. For example, extreme of 5 and -10 is -10.
