General Studies · Finite Element Analysis
An isoparametric element is mapped from the physical coordinate system to natural coordinate system. If the element is severely distorted, how does it affect the Jacobian determinant?
- 1The Jacobian determinant remains constant at -1 everywhere.
- 2The Jacobian determinant is unaffected by spatial distortion.
- 3The Jacobian determinant value varies and can become negative or zero depending on the coordinates.✓
- 4The Jacobian determinant increases uniformly at all nodes.
Correct answer
The Jacobian determinant value varies and can become negative or zero depending on the coordinates.
