removeBEonCondition{

remove boundary elements based on a (mathematical) condition

For the given geometrical entity (file or AliasName), boundary elements are deleted, if they fulfill a given condition. The conditions can be based on the geometry of the node points or the center of gravity Additional conditions might be possible based on the layer, the size of the boundary element etc. (see the list below)

begin_boundary_elements{} include{FileName} removeBEonCondition{ %GEO_removeBasedOnNodes% | %GEO_removeBasedOnCOG% , [ equationText ] } # remove boundary elements if evaluation of the given equation returns a positive number ... manipulate{"AliasName"} removeBEonCondition{ %GEO_removeBasedOnNodes% | %GEO_removeBasedOnNodes% , [equationText ] } # remove boundary elements if evaluation of the given equation returns a positive number ... end_boundary_elements

examples:

manipulate{"AliasName"} removeBEonCondition{ %GEO_removeBasedOnNodes% , [ Y%ind_x(3)% > 0.8 ] }

-> delete element, if the z-components of all of the node points are bigger than 0.8

manipulate{"AliasName"} removeBEonCondition{ %GEO_removeBasedOnCOG% , [ Y%ind_x(3)% > 0.8 ] }

-> delete element, if the z-component of the center of gravity (COG) is bigger than 0.8 Additional conditions are possible using the items

nromal information -> Y%ind_n(1)% , Y%ind_n(2)% , Y%ind_n(3)%
area -> Y%ind_dA%
layer information -> Y%ind_layer%
boundary condition information -> Y%ind_BC%
movement information -> Y%ind_MOVE%
index of boundary element -> Y%ind_BE1%

IMPORTANT: The user connot use predefined equations here, so the construct

begin_equation{"z_limit"} Y%ind_x(3)% > 0.8 end_equation begin_boundary_elements{} manipulate{"AliasName"} removeBEonCondition{ %GEO_removeBasedOnCOG% , [ equn($z_limit$) ] } end_boundary_elements

will not work, as equation definitions are not yet read at the time of BE-read-in.
