Incorrect Definition of Surface

Post by yjin » Thu Sep 20, 2018 3:13 pm


I am working on generating FE mesh for my model. I received a error notification shows below telling I have an incorrect definition of a surface. I have no idea what it means and how to solve it.

Thank you,

Hi Yufan,

this is not a simple problem - see my comments in attached Yufan_01.pdf. Even if you fix surface #23 (see also the attached fixed project, there are more topological problems that must be fixed. The domain is really complex and you must have spent a lot of time with it. I believe that we could create some new tools/methods for domains like this one in the new version of HYDRUS (version 3.01 - It would help us, if we had more information about your original input data, i.e. the format of your topological data + information about material distribution (geo-layers). If you decide to send us this information, please send it to
