If the forming contact is used, the automatic reorientation of contact interface segments during initialization is selected automatically. However, the above mentioned problem might happen under the following two conditions:
1. The element normal of the rigid body is not pointing to the blank. In this case, with forming contact, LSDYNA will automatically change the normal to the blank.
2. If *CONTROL_ADATIVE is used, and the parameter ORIENT is chosen to be 1, then the automatic reorientation capability available in LSDYNA is disabled.
If conditions 1 and 2 exist at the same time, LSDYNA will find the wrong contact surface.
