Case 6 Assigning Property Dependencies (Spatial_table)

 

In this exercise Young's  Modulus will be defined to be dependent on porosity by using the Spatial_table data structure. In order to observe its effect a distribution by bands is defined. Note that if Young's Modulus is going to be defined as dependent on porosity, Poroelasticity must not be active in the material.

 

To perform this exercise copy the datafile from Case5 as a template. Then:

1Delete the Poroelasticity data from Shale_CF75 properties.

2Define the Spatial_table as shown bellow.

1In Spatial_table the variable "Young" is defined to depend on "Porosity" for material Shale_CF75.

2It is specified that Porosity is defined by the spatial grid "Porosity_Spatial" .

3Ten Young's Modulus values are provided for different porosity values.
