Initialization

Initialization is essentially the first step of the Abaqus simulation run. It establishes an initial stress state for the entire 3D mesh (overburden, reservoir, sideburden and underburden), by calculating the equilibrium between gravity, density and the initial stress states. Initialization is carried out separately from the actual simulation run to avoid substantial changes occurring at the very start of the run. With the initialization process, the effective stress ratios (ESRs) are also applied to ensure the model does not only have the correct vertical stress, but also the correct horizontal stresses and orientation at the start of the simulation. The result of initialization is a model in the correct initialized equilibrium state, stored in a new case called <case name_initialized>.

1. At the top of the form, select the Abaqus case of interest.
2. From the Simulator drop-down list, select the Abaqus version of your choice. You can select the Browse option and navigate to the location of the simulator executable (*.exe) on your machine. Once specified, the application will save the location for the executable.
Using Browse also allows you to select versions of Abaqus that are not officially supported in JewelSuite. This can lead to unexpected behavior or failed simulations. It is strongly recommended to use the listed versions unless none of them are suitable.
3. Select the number of processors designated to work on the simulation job. The number you select depends on the size of your model.
4. Click Apply to save your settings and keep the form open, or click OK to save your settings. This will run the initialization simulation in Abaqus and applies the stress ratios. Close the form and go to the next step in the workflow, Create Pore Pressure.
