Overview

The objective is to re-perform the simulation using the permeability (k) = 1.0E-19m2.  This is achieved by defining a new material in the hm_002_elastic.mat file called hm_002_elastic_1E19 and then changing the data file to read this data.  The example data is provided in HM_002\Exercises\Case 2\Data\hm_002_Case2.dat.

 

Results

The result files for the project are in directory: HM_002\Exercises\Case 2\results and the high definition history files can be displayed in excel file hm_002_Case2.xlsx.   The evolution of pore pressure and effective stress are shown below.   The predicted maximum overpressure at the base of the column is ca. 6 MPa which is higher than analytical prediction.  This is expected and is due to the longer drainage path associated with the pre-existing sediment assumption.
