dm | - the DM | |
cell | - the cell | |
quad | - the quadrature containing the points in the reference element where the geometry will be evaluated. If quad == NULL, geometry will be evaluated at the first vertex of the reference element |
v | - the image of the transformed quadrature points, otherwise the image of the first vertex in the closure of the reference element | |
J | - the Jacobian of the transform from the reference element at each quadrature point | |
invJ | - the inverse of the Jacobian at each quadrature point | |
detJ | - the Jacobian determinant at each quadrature point |
