Plaxis 3d problem

The problem is this ---- "Error: DET<0" in the 1 phase
the answer from faq on plaxis site is

=====This error in iterative solver can be caused by:

*1- Not enough memory (or too many elements for the current memory)
* 2- Badly shaped elements: good elements are those with the same size for width, length and height of the element.
*3- Large stiffness differences in your model (e.g. a difference ratio > 1E6). This also includes the use of structures (beams, walls)

So please check your mesh (both 2D and 3D) in detail, and check if you use large stiffness differences in the used materials. Sometimes a hint is given by the program: if you e.g. activate a plate in phase 4, and this phase shows the error, it is likely that the used stiffness for the plate is too high for the numerical model.======

for *1 i have 4gb ram
for *2 all the piles have the same size
for *3----well this is the problem...i do not fully understant want they want to say.......i use this pb for about 2 weeks so i am new at this......

maybe someone can help me with an answer or to resolve the problem
i have atached the work files
thank you in advance

Your model is working. But you must add a borehole.

Good Luck
