Description
Linear tetrahedron for generic constitutive laws.
Can be used for multiphysics. Because of linear interpolation, some closed form ad-hoc expressions are used here for J, dNdX, etc., aiming at higher performance.

Member Function Documentation
◆ ComputeJ()
|
overridevirtual |
Compute Jacobian J = dX/dη, and returns its determinant.
Compute Jacobian J = dX/deta, and returns its determinant.
FALLBACK default implementation; but if possible implement a faster ad hoc computation.
Reimplemented from chrono::fea::ChFieldElementVolume.
◆ Update()
|
inlineoverridevirtual |
Update, called at least at each time step.
If the element has to keep updated some auxiliary data, such as the rotation matrices for corotational approach, this should be implemented in this function.
Reimplemented from chrono::fea::ChFieldElement.
