Introduction

This page contains information about ponding.

Since 2023 ponding is implemented in XFEM4U.

The theory of the implementatie of ponding is according to the scientific insights of prof. Blaauwendraad. In the latest Heron Journal this method is implemented described in detail. Link to heron journal
