4 Two major improvements are implemented for peak smoothing region.

6 (% style="text-align: justify;" %)
7 Firstly, **finite element mesh is not adjusted to peak smoothing region**, so the FE mesh will be more efficient. From now on, only the nodes within the peak smoothing region will be considered into the internal force modifications.

34 Nodal results within the peak smoothing region are constant.

36 This is exactly the same as in previous versions.

38 |=Use higher order shape functions|(((
39 Nodal results within the peak smoothing region are not constant,
40 but distribution of internal force is a higher order function.
