Hi Jiahao,

Thank you for reaching out to us and asking this question! May I ask you whether you have come across this post: Topology inverse design mesh interpolation. One of our users have a similar question and a colleage of mine has provided a detailed response there. 

Let me know if that covered you or you would like further assistance.

Kind Regards,

Niki
