Comments
- The default (blank line) reference state file name is RunnameRS0.
- A reference state file contains the reference coordinates of the nodes (input format is the same as for node coordinates in /NODE option; lines starting with # are comment lines).
- A reference state file does not necessarily contain the coordinates of all nodes in the model. If no coordinates are given for a node, initial coordinates are used instead.
- Enhanced reciprocity will be obtained if Nitrs is increased.
- Reference state is available:
- for shells using /MAT/LAW1 (ELAST), /MAT/LAW19 (FABRI) or /MAT/LAW58 (FABR_A)
- 4-node tetrahedron elements using Iframe =2 (co-rotational formulation)
- 8-node bricks using Isolid =1, 2 or 24 and Iframe =2
- material laws /MAT/LAW35 (FOAM_VISC), /MAT/LAW38 (VISC_TAB), /MAT/LAW42 (OGDEN) or /MAT/LAW70 (FOAM_TAB)
