*AIRBAG_PARTICLE: Added IAIRSTAT, DPWR, and VNDAMP to Card 5.1. Added Remark 19. Updated definition of LCPC23 on Card 10 to allow *DEFINE_FUNCTION.

*CONTACT_OPTION: Added IGTOL to MPP2 including a remark and figures.

*CONTROL_IMPLICIT_EIGENVALUE: Added EIGMSCL to Card 4.

*CONTROL_IMPLICIT_SOLVER: Added that LSOLVR = 22 becomes a GMRES solver when LPACK = 3. Also added statement to the first paragraph of Remark 8 about how LPACK = 3 interacts with the different solvers.

*CONTROL_SOLID: Removed restriction that TET13K was not available in MPP from the description.

*CONTROL_SPH_INCOMPRESSIBLE: Added IRMV and ACMP.

*CONTROL_2D_REMESHING_REGION: Added LTYP = 10.

*DAMPING_FREQUENCY_RANGE: Added field ICARD2 to Card 1 to flag for reading an additional card. Added Card 2 for this case. Added Remarks 4 and 5. Rearranged the rest of the remarks section.

*DATABASE_HISTORY_OPTION: Added keyword options DES and DES_SET. Added Remark 3. Updated the purpose and description of IDn on Card 1a for these new keyword options.

*DATABASE_OPTION: Added keyword option SNSROUT and DEBOND.

*DEFINE_CPM_VENT: Updated defintion of LCPC23 to allow *DEFINE_FUNCTION.

*DEFINE_CPM_SWITCH_REGION: Added HEIGHT so the region can be cylindrical.

*DEFINE_DE_TO_SURFACE_COUPLING: Added ISOFT to Card 1.

*DEFINE_DE_BOND: Added BENDSF to Card 2. Added Remark 6.

*DEFINE_DE_BOND_OVERRIDE: Added BENDSF to Card 2. Added Remark 4.

*DEFINE_SPG_TO_SURFACE_COUPLING: Removed restriction stated in the purpose that this keyword was only available for SMP.

*DEFINE_SPH_AMBIENT_DRAG: Added ICPL = 1 (ICPL was previously called ICID). Added Card 2 and example 1.

*DEFINE_SPH_INJECTION_SIMPLIFIED: New keyword.

*ELEMENT_BEAM_SOURCE: Added NCUT.

*SENSOR_DEFINE_ELEMENT: Added COMP = HYDR, MAXS, PRIN1, PRIN2, PRIN3, VM, and F[ID].

Error Fixes and Clarifications
==============================

*CONTACT_OPTION: 
   1) Added to description for SBOPT = 4 and 5 (Optional Card 5) that it is not recommended with DEPTH = 5, 25, and 35. Added subsection edge treatment to About SOFT = 2 in the remarks following Optional Card A. Added clarifications about SBOPT = 4 and 5 (sliding option) to subsection Fields used with SOFT = 2 of section About SOFT = 2. Added Figure 11-17 to illustrate these additions for the sliding option.

   2) Fixed Table 11-2 to reflect the correct release criterion for contact types a3, a5, a10, 13, and 15. Fixed description of PENMAX on optional Card B to have the correct defaults for contact types a3, a5, a10, 13, and 15. 

*CONTROL_IMPLICIT_MODAL_DYNAMIC_DAMPING: Fixed incorrect purpose.

*CONTROL_OUTPUT: Updated description of SPC2BND to clarify the value of the flag that makes it active.

*DATABASE_FREQUENCY_BINARY_OPTION: Added details to remark 4 about the states in d3spcm.

*DATABASE_RVE: Removed BINARY = 1  (binary file output) as it is currently not available for rveout.

*DEFORMABLE_TO_RIGID / *DEFORMABLE_TO_RIGID_AUTOMATIC: Added two warnings to the top that these keywords can only be used for switching between finite elements and rigid bodies and that *PART_MODES is not supported with these keywords.

*DEFINE_SPH_INJECTION: Added missing description of NID.

*FREQUENCY_DOMAIN_RANDOM_VIBRATION: Fixed error in Remark 7. UNIT should have been -1 instead of 3 in the second paragraph of the remark.

*FREQUENCY_DOMAIN_SSD: Added clarification to the definition for PID Card 5 about the available types.

*INTERFACE_LINKING_EDGE: Fixed error in the purpose where it said interface force file instead of interface file in the first sentence.  

*INTERFACE_LINKING_NODE_OPTION: Added warning that nodes constrained by the linking file cannot be in other constraints

*SENSOR_DEFINE_ELEMENT: Clarified that COMP = XX, YY, ZZ, XY, YZ, and ZX apply to thick shells. Also clarified that CTYPE = STRESS and STRAIN apply to thick shells.
