Problem with spring-like smoothing

benjo

Hi, I am using dynamic mesh and I smooth with the help of the spring method, the problem is that some of the cells become very large and other become strangly strach and they often shrink to diffrent shapes, I think that remesh or layering will solve the problem but I can mange to use that methods altough I tag that options in the dynamic mesh configurations. Maybe it is becuase I am used qud cells with the cooper method to mesh my geometry ?

I will totaly appriciate your help.
