Dear all,
I'm a little bit confused about some points in this example and would appreciate any help.
1- In this example, for initialization, we are using External Stress in solid2 and step#2 (from gravity analysis in solid and step#1), but solid2 again considers gravity! If we are using stresses from the gravity analysis in step1, shouldn't we remove gravity from solid2?! Having both External Stresses and gravity in solid2 does not double the response?
2- For initialization, we are just considering external stress?! What about displacement (strains)?
3- And finally, in the results part, everything is based on sol1 (Data/Data set/study 1/solution 1 (sol1). What about sol2? shouldn't "after excavation" results be based on sol2? If not, then what is the point of having sol2 in te drop-down menu of Data/Data set?
Thanks in advance for your help. Regards, Ramin
