Notes

The BSMD command, one of several nonlinear general beam section commands, specifies the mass density (assuming a unit area) for a beam section. The value specified is associated with the section most recently defined (via the SECTYPE command).

If DENS is unspecified, it defaults to zero. If the temperature is unspecified, DENS becomes temperature-independent.

Related commands are BSAX, BSM1, BSM2, BSTQ, BSS1, BSS2, and BSTE.
