Member Function Documentation

getForceAtNode2() [1/2]

virtual double sel::ISEL::getForceAtNode2 ( uint32 dof, uint32 end, bool local = false ) const

pure virtual

Returns one component of force exerted by a given node on the structural element.
Valid values for dof are [0,5] - e.g. 0 = translational x, 3 = rotational x
Valid values for end are in the range 0 to getNumNd()-1.
local set to true returns nodal force in element local coordinate system,
otherwise it returns nodal force in the global coordinate system.

getForceAtNode2() [2/2]

virtual DVect sel::ISEL::getForceAtNode2 ( uint32 end, bool trans, bool local = false ) const

pure virtual

Returns force exerted by a given node on the structural element.
Valid values for end are in the range 0 to getNumNd()-1.
If trans is true, then return force, else return moment.
If local is true, then force is expressed in element local coordinate system,
otherwise, force is expressed in global coordinate system.

getMaterialSys()

virtual Axes sel::ISEL::getMaterialSys ( ) const

pure virtual

Returns local axes system for ortho/anis material properties.
Only valid for shell-type SELs.

getNext()

virtual const ISEL * sel::ISEL::getNext ( ) const

pure virtual

Returns const pointer to next ISEL object from the global list of SELs,
or 0 for the last element of the list. See ISELList::getFirstSEL().

getYieldName()

virtual string sel::ISEL::getYieldName ( YieldState state ) const

pure virtual

Returns name of nodal yield state for this structural element.
Possible values are no, now, past .
