Hey,
I am trying to calculate pullout capacity of a suction caisson for my thesis at the end of Aug.
I am new at using Plaxis (less than a month) and I've found a tutorial on plaxis website. I have followed it through and got results. However, the plaxis tutorial did not consider the thickness of the pile so I added an inner surface with a smaller radius (3.92 m).
Tried to generate mesh and this error came up
Meshing failed with the following error:

I have also tried to add wings to the caisson and a similar error came up.
In addition, how do I add load to the structure at different angles (0, 30, 45, 60, 80, and 90) ?
I look forward for the feedback
Does the gap between the inner circle and the outer circle filled automatically or I have to create a top surface for it? also, it is quite impossible to create a continuous structure to avoid gaps
It depends. But if the object is annular, you need to create a surface between the inner and outer circle to fill up the gap between them.
thanks
