Custom Field Stress

There are situations when it is required that the user be able to specify the field stress for individual materials in a model, rather than only a single field stress which applies to all materials.

For example, individual layers of material in bedded geological structures, will sometimes have a field stress which is different from the field stress in surrounding layers. When this situation occurs, you can define a custom field stress for any material(s) in the model, as follows:

1. In the Field Stress Properties dialog, select the Advanced button.
2. The dialog will expand, allowing you to define a customized field stress for any material(s) in the model. Note that the materials in the Field Stress Properties dialog correspond to the materials you have defined in the Define Material Properties dialog.
3. To define customized field stress for a material, select the Apply Custom Field Stress check box for the desired material, and enter the field stress parameters which apply to the material.
4. Repeat Step 3, for each material which requires a custom field stress.

NOTE: the default field stress properties, in the main (upper) part of the Field Stress Properties dialog, will still apply to all materials which have NOT had custom field stress properties specified.
