Dry Modes are now output to the H3D file when MFLUID is used with PARAM, VMOPT,2.

The values of ERPREFDB and SPLREFDB are calculated based on the UNITS entry unless PARAM, ERPREFDB or PARAM, SPLREFDB are specified explicitly. When the UNITS entry and the PARAM’s are not present then the values are set equal to 1.0.

Radiation loss factors used in the equivalent radiated power (ERP) calculation can now be specified on the PANELG bulk data entry through the ERPRLF field. A real value can be specified to directly define the loss factor for all frequencies, or an integer value can be specified to reference a TABLEDi entry that defines the loss factor vs frequency table.

The Automated Transfer Path Analysis process is now enhanced with stability and accuracy improvements, SPCD support, and Direct Frequency Response Analysis support. The grids on the control volume are automatically output to the ASCII file.

If MDK4OPT=1, the most common value of GE for structural elements may be internally set equal to PARAM, G to speed up the calculation of material damping. The traditional material damping calculation method is used, if MDK4OPT is set to 0.

RVDOF and RVDOF1 bulk data entries can now be used to specify degrees of freedom where the residual vectors are to be calculated to enhance the modal space.

Preloading is now supported and can be applied to Modal Frequency Response Analysis and Direct/Modal Transient Response Analysis subcases by specifying STATSUB(PRELOAD).

Modal Frequency Response solution has been enhanced with the support of long integer pointer usage to utilize all available memory to run large models.

The performance of the Craig Bampton (CB) method has been enhanced for Component Mode Synthesis (CMS) Analysis.

Normal Displacement, Normal Velocity, and Normal Acceleration outputs are now available for Frequency Response Analysis. “Normal” indicates that the direction of output is normal to the surface on which a grid is present. DISPLACEMENT(NORMAL), VELOCITY(NORMAL), and ACCELERATION(NORMAL) entries can be used to request the corresponding normal results. Normal results are automatically only output for grids on the surface of the model or given grid set.

Grids from the 2nd Round of AUTOSPC is output to the .HM.autospc.cmf file. If it is an optimization run, this is executed only in the first iteration.

Non-Structural Damping is now available via the NSGE, NSGE1, and NSGEADD bulk data entries which are referenced by an NSGE subcase information entry. The NSGE and NSGE1 bulk data entries define non-structural damping per unit area or per unit length for a list of elements, properties, or element sets. The NSGEADD entry defines non-structural damping as a sum of defined NSGE and/or NSGE1 entries.

Specified CBUSH elements can be included or excluded from Residual Vector calculations using the VISC_INC and VISC_EXC options, respectively on the RESVEC subcase information entry. The VISC_INC and VISC_EXC options can reference CBUSH element set identification numbers for inclusion or exclusion.

Residual vectors are now calculated when static loads are used in Lanczos run.
