Topic: CCFEModelExc: Negative or zero value of element Jacobian: -1.36298e-00
Hi,
I am using ATENA3Dv4 for modelling multicylinder wellbore. I have given input of my pressure load in 36 load steps. After running for 12 steps i.e at 13 th step solution killed by an error as - "CCFEModelExc: Negative or zero value of element Jacobian: -1.36298e-006, in element id: 138, group id: 410517506, name: Quadratic Tetra elements(1937) for Macroelement 2".
Can you please advise me on this ?
regards.
