getdisp（）

[tangzhen]

why i get 0 when i use the getDisp() class in element. is there any thing i forget?

[tangzhen]

i used theNodes[0]->getDisp()

[fmk]

it returns a const Vector, does that Vector contain 0's .. if so the committed displalecements of the node are 0, so either node has not moved or is back at it's original position.

if this is the first step and you are looking for trial displacements instead of committed displacements, ise getTrialDisp() instead.
