Dear Guillaume,<br>
Dear Jean,<br>
<br>
Thank you very much for your advice! <br>
<br>
As Jean suggested, the surface is not closed. I turned the .msh file
to stl so that I could visualize in paraview.<br>
I fix this by creating a script to check if every element is
surrounded by neighbour or bounding line and it works.<br>
<br>
Thanks again and best regards,<br>
Jarunan<br>
