How to access the positions of isosurface by UDF

Hi guys

My recent work make me to access the positions of each points of the iso-surface when I descripts the DEFINE_EXECUTE_AT_END macrons. I have searched for the solution in this forum and I still have no idea.

I need your helps and any suggestion and assistant will be appreciated.

Thanks

I have an idea about this topic. I can calculate iso-suface at DEFINE_EXECUTE_AT_END with the iso-value and coordinates of the grid by interpolation. But I can not access the node variables and this method is of less accuracy and more time-cost.

Please show me some better ideas. Thanks!
