PRSCONTROL, Key
Specifies whether to include pressure load stiffness in
the element stiffness formation.
KeyPressure load stiffness key. In general, use the default
setting. Use a non-default setting only if you encounter convergence
difficulties. Pressure load stiffness is automatically included when
using eigenvalue buckling analyses (ANTYPE,BUCKLE),
equivalent to Key = INCP. For all other
types of analyses, valid arguments for Key are:
NOPL | — | Pressure load stiffness not included for any elements. |
(blank) (default) | — | Include pressure load stiffness for elements SURF153, SURF154, SURF156, SURF159, SHELL181, PLANE182, PLANE183, SOLID185, SOLID186, SOLID187, SOLSH190, BEAM188, BEAM189, FOLLW201, SHELL208, SHELL209, SOLID272, SOLID273, SHELL281, SOLID285, PIPE288, PIPE289, and ELBOW290. Do not include pressure load stiffness for elements SOLID65. |
INCP | — | Pressure load stiffness included for all of the default elements listed above and SOLID65. |
