 By default, if  $n$  is the degree of mechanical interpolation and  $d$  the element dimension, the number of integration points in the deviatoric part of the stress field is  $(n+1)^{d}$ , unless stated otherwise with the definition of ''NIPDKSI'', ''NIPDETA'' or ''NIPDZETA'' (see [[#Parameters ]]). \\ For example, the interpolation of ''Volume2DElement'' is of the first degree ( $n=1$ ), and it is a 2D element ( $d=2$ ), leading to 4 integration points.
-The number of integration points in the volume part of the stress field (pressure) depends on the chosen [[doc:user:elements:volumes:elements_formulation|method to integrate stresses]] are cannot be modified.

 ===== QuadVolume[2|3]DElement =====
-''QuadVolume2DElement'' and ''QuadVolume3DElement'' are quadratic elements. ''QuadVolume2DElement'' is a 8-nodes quadratic quadrangle, ''QuadVolume2DElement'' a 20 quadratic hexaedron. They are purely mechanical, with respectively 16 and 60 dofs.

 By default, stresses are integrate over 4/27 integration points in the deviatoric part in 2/3D, with the formula already stated for ''Volume[2|3]DElement''. The standard formulation must be used (''CAUCHYMECHVOLINTMETH = VES_CMVIM_STD''), which is not the default one.
