hello dear,
i am new usre of abaqus, i try to model tunnel adjacent to reservior
my model:
- 2D model
- BCs: boundary of tunnel and reservior with rock assume be rigid (model with analytical rigid and tie to tunnel and reservior),
upstream of reservior have impedance and free surface of reservior have zero pressur.
steps: initial, dynamic implicit
- Load: earthquake acceleration apply to rigid boundary
at last when i submitted job this error were shown : The elements contained in element set ErrElemExcessDistortion have distorted excessively.
help me plz
