PARAM, HOURGLS

Bulk Data Entry Controls the hourglass type.

Parameter Values Description
HGTYP <1, 2, 4> Hourglass control type.
1
Flanagan-Belytschko viscous form (available both solids and shells).
2 (Default)
If HGTYP=2 is defined for solids: Puso enhanced assumed strain stiffness form (available only for eight nodes CHEXA elements.
If HGTYP=2 is defined for shells: Flanagan-Belytschko stiffness form (available for shells only).
4
Reese enhanced assumed strain stiffness form (available only for eight-noded CHEXA elements).
HGFAC

 Scale factor for hourglass control forces.

Comments

  1. HOURGLS entry referenced on HGID field of PSOLID, PLSOLID, or PSHELL will overwrite the values defined via PARAM,HOURGLS.
