*ENDPY – Terminates a block of content that is interpreted as Python commands.

*PYTHON – Initiates a block of content that is interpreted as Python commands. Use the APDL process control commands, *PYTHON and *ENDPY, to add Python code directly in a Mechanical APDL input listing.

BF – Defines a nodal body-force load. The command now supports temperature body-force loads on MESH200 elements using the mesh-independent method.

BFE – Defines an element body-force load. The command now supports temperature body-force loads on reinforcing and MESH200 elements.

BFINT – Activates the body force interpolation operation. Use the new Fmat argument to define the output file format (default is the blocked format).

BFPORT – Transfers body-force loads (heat generation, temperature, and body-force density) from selected MESH200 elements to reinforcing elements. The command now supports temperature body-force loads on reinforcing elements.

CMBLOCK – The argument KOPT now supports SMART crack-growth analysis with Entity = ELEM and NODE and it is limited to solid element components and surface node components.

LANBOPTION – Specifies Block Lanczos eigensolver options. Use the new Memory_Option, MININCORE to drastically minimize memory usage when your hardware configuration has limited memory resources.

RADOPT – Specifies Radiosity Solver options. Use the new STABILIZATION argument to enable stabilization terms of the nonlinear temperature-dependent convection film coefficient and improve convergence behavior.

SFCONTROL – Defines structural surface-load properties on selected elements and nodes for subsequent loading commands. Use the new short input format to enter a single label (surface-load property) and value.

TBFT – Performs material curve-fitting operations. The material models for curve-fitting now include shape memory alloy. The TBFT,SET command now supports partial solver options to set the reference temperature with Option4 = COMP and Option5 = PSHEA (to solve only for Shear Modulus parameters) or PBULK (to solve only for Bulk Modulus parameters).

VFUP – Controls view factor updating at the substep level for a coupled-field radiation analysis that includes large-deflection effects. Use the new options, KNEX, KNIM, and KNI1, to specify kinematic-based view factor updating criteria to update only if geometric changes to radiation surfaces surpass specified thresholds.
