i got a model node in slicer , is there any extension or any algorithm to make the surface of the modelnode smooth?

You can use the smoothing and remeshing options in the Surface Toolbox.

You can probably use the dynamic modeller and plane or curve cut to split your model into two parts, and smooth the part you would like to more. Then use the mergeModels to put them together…
