define smoothing kernel for smoothing of surface curvature
Surface curvature is smoothed in each time cycle, The raw curvature might be noisy, so smoothing is maybe appropriate.
\begin{align} \kappa^{k}_i = \frac{ \sum \limits_j^{N_i} W_{ij} \kappa^{k-1}_j }{ \sum \limits_j^{N_i} W_{ij} }\end{align}
with \( k = 1...\text{SURFACETENSION\_NbSmooth}\)
The smoothing kernel is defined as
\begin{align} W_{ij} = exp \left( -\text{SURFACETENSION\_FacSmooth} \cdot r_{ij}^2 \right)\end{align}
