getBasicIncrDisp vs. getBasicIncrDeltaDisp

[cenk tort]

Hello ,

I am not sure about the difference between the functions "getBasicIncrDisp" and "getBasicIncrDeltaDisp" at the element interface. I am assuming that "getBasicIncrDisp" is for incremental displacements at the natural coordinate system and "getBasicIncrDeltaDisp" is for the iterative displacements at the natural coordinate system. Does anybody have a comment on this ?

Thanks.

There are no such methods in the Element interface itself, you must be looking at a particular subclass. The corresponding methods at the Node interface and their description, which i suspect are similar, are as follows:

the getIncrDisp() returns the difference between the current trial displaments and the last committed displacement. The getIncrDeltaDisp() returns the difference between the current trial displacement and the last trial displacement.
