Bulk Data Entry
GAPPRM – Parameters for Gap Element Connectivity and Configuration Checks
Description
Defines parameters that control connectivity and configuration checks for gap elements (CGAP and CGAPG). Most of these parameters also affect contact elements that are automatically created on CONTACT interfaces – see individual descriptions for details.

| 1. | The GAPPRM entry changes the default settings of control parameters for the gap elements connectivity and checks for configuration errors. None of the parameters of this entry are required. |
| 2. | The gap alignment check controlled by the default value of CKGPDIR = ERR applies correctly to the most typical situations wherein there is an initial opening between bodies A and B, and the gap element is used to enforce non-penetration condition. For cases of overlapping meshes (combined with a prescribed coordinate system), the REV value is appropriate – it allows both aligned and reversed gap directions (respective to the gap axis defined by the prescribed system). |
