Topic: Construction Case error
I am trying to model a prestressed girder with a deck on top.
The deck on top is casted only after the prestressing is applied on the girder, accordingly I specified a separate construction case where the top deck is activated and self weight is applied using a body force load case.
The top deck and the prestressed girder share a partial contact (perfect connection).
In my analysis steps, the prestressing and self weight of the girder are first applied followed by the application of selfweight of the deck.
The analysis runs fine till the application of prestress and selfweight of the girder but in the step where the top deck is activated i am getting the following error.
(Thread 1) CCFEModelExc: Negative or zero value of element Jacobian: -0.923061, in element id: 18706, group id: 403177475, name: Tetra elements(410511) for Macroelement 3
Source line: 303, file: C:\AtenaV540\Sources\Include\CCIsoElement\calculate_element.h
Also I wanted to mention that I use ATENA 3D for building my file and export the input file to run it in ATENA Studio as the problem size is large.
