Please allow me to add one question about the drainage in submerged saturated soil. I try to use the "Phreatic Surface", but it seem doesn't work . The hydrostatic head of bottom in the model is the height of saturated soil. How to set the free water surface correctly? Hope for your suggestions. |

Dear Tu, If you want to reuse the files in another folder, you need to edit the calculate.BAT file (right click on it and Edit) and include the path of the new directory and executable. Submerged analysis will not work together with a phreatic surface, but the whole model is assumed in submerged conditions. In this case, the code uses an equivalent submerged unit weight and only excess pore water pressures are computed. I hope this helps. |

Thank you for your prompt answer. It really helps me. But I haven't figured out the problem about drainage in submerged soil, perhaps because I haven't explained the problem clearly. If the option of "Submerged Calculation" is not open and the phreatic surface located above the saturated soil surface is applied, Is the hydrostatic head equal to the height of the phreatic surface or soil surface? (The bottom of soil is selected as the datum of the position head) |

I have tried to simulate a saturated soil model with phreatic surface. The results show that the hydrostatic head is equal to the height of soil surface. |

And I found that there is an option "Reset displacement" in the "Calculation Data"dialogue box. Will the displacement of the material points be reset after each calculation step (or load step)? |
