Troubleshooting Legacy Models

2.4. Troubleshooting Legacy Models#

  1. The search tolerance for Sierra/SD Tied Data must be set carefully to ensure that the same nodes that are in contact as in Sierra/SM.

    1. Use very small search tolerance, in the range of one to two orders of magnitude smaller than the capture tolerance in Sierra/SM should be sufficient.

    2. Ideally, nodal contact information should be passed directly from Sierra/SM to Sierra/SD (not currently available).

  2. The sidesets used to define the tied contacts in Sierra/SD must be defined in the input Exodus file used by Sierra/SM, even if they are not used in Sierra/SM.

  3. The material properties for each element are not passed from Sierra/SM to Sierra/SD. This is important with nonlinear models.
