Negative Jacobian error message on Modal Analysis
Negative Jacobian error message on Modal Analysis
(OP)
Every time I attempt to run a modal analysis on my model I get the error message:
* * * E R R O R * * * (WHILE RUNNING ANALYSIS)
NEGATIVE JACOBIAN ENCOUNTERED,
CHECK ELEMENT CONNECTIVITY AND JOINT COORDINATES FOR ELEMENT 1147
Now, I have two questions. How could I find an element in etabs and someone knows why did it happened this error.
