PROBID PROBID Problem-id OPERAND DESCRIPTION DEFAULT Problem-id Sets the Problem ID during the processing of keywords None DEFINITION The PROBID variable Sets the Problem ID during the processing of keywords. REMARKS It is an action keyword placed in either an automatic script file or in a Master file. The purpose of PROBID is to set the problem id during the processing of a master file in order to specify the database to be read and/or written to. RELATED TOPICS Multiple Operations PRZ PRZ Object, DefPressureX, DefPressureY, DefPressureZ, Ndata Node(1), Pressure(1) : : Node(Ndata), Pressure(Ndata) OPERAND DESCRIPTION DEFAULT Object Object number None Ndata Number of node/traction data pairs None DefPressureX Default value of distributed nodal traction in X direction of all nodes not listed in the node/traction pairs with deformation boundary constraint code 2 DefPressureY Default value of distributed nodal traction in X direction of all nodes not listed in the node/traction pairs with deformation boundary constraint code 2 DefPressureZ Default value of distributed nodal traction in X direction of all nodes not listed in the node/traction pairs with deformation boundary constraint code 2 Node(i) Node number of i th data pair None Temp(i) Nodal traction of i th data pair 0.0 DEFINITION PRZ maintains a specified normal pressure or shear traction across the face of the elements lying between the selected boundary nodes. REMARKS Pressure is defined as force per unit area. The pressure is assumed to be linear between adjacent nodes as shown in Figure 6.9 on page 6-68. The pressure constraint will be applied to the element faces lying between the selected boundary nodes. The pressure direction may be specified as normal or shear. Positive normal pressure applies tension to the element faces. Positive shear traction is defined by the right hand rule. If no value is specified for DefPressureX, DefPressureY, or DefPressureZ, it is assumed to be zero. Nodal pressure values may only be applied to nodes which have deformation boundary constraint code 2 (BCCDEF). Nodal pressure may be specified as a function of time with keyword BCCFCN.

REMARKS REFPOS is to be used in conjunction with MDSOBJ which sets the distance between two objects. REFTMP REFTMP Object, RefTmp OPERAND DESCRIPTION DEFAULT Object Object number None RefTemp Reference temperature of the object 20  C or 68  F DEFINITION REFTMP specifies the reference temperature at which the geometry of the object is defined.

REMARKS Applicable object types: Rigid, Elastic, Plastic, Elastoplastic, Porous RELATED TOPICS Boundary constraints, Inter-object contact Keywords: DATOM, BCCCRB RMDPTH RMDPTH Object, RDepth OPERAND DESCRIPTION DEFAULT Object Object number None RDepth Interference depth at which to initiate automatic 0.0 remeshing procedure DEFINITION RMDPTH controls the initiation of a remeshing procedure based on the stroke of the primary object. REMARKS There are four keywords that control the initiation of a remeshing procedure (RMDPTH, RMTIME, RMSTEP, RMSTRK) for an object. When the remeshing criteria of any of these keywords has been fulfilled or the mesh becomes unusable (negative Jacobian), the object will be remeshed. RMDPTH controls the initiation of a remeshing procedure based on the depth of interference between a slave object and a master object. The depth of interference is the depth an element edge of the slave object is crossing the surface of a master object. The object to be remeshed must be a slave object. If RDepth = 0, the interference depth will not be used to determine when the object is remeshed. Applicable object types: Plastic, Porous RMSTEP RMSTEP Object, RStep OPERAND DESCRIPTION DEFAULT Object Object number None RStep Simulation step increment at which to initiate an 0 automatic remeshing procedure DEFINITION RMSTEP controls the initiation of a remeshing procedure based on the number of simulation steps measured from the last remeshing. REMARKS There are four keywords that control the initiation of a remeshing procedure (RMDPTH, RMTIME, RMSTEP, RMSTRK) for an object. When the remeshing criteria of any of these keywords has been fulfilled or the mesh becomes unusable (negative Jacobian), the object will be remeshed. RStep is the value of simulation steps allowed to elapse between remeshings of the object. If RStep = 0, the number of steps between remeshings will not be used to determine when the object is remeshed. Applicable object types: Plastic, Porous RMSTRK RMSTRK Object, RStroke OPERAND DESCRIPTION DEFAULT Object Object number None RStroke Stroke increment of primary object at which to 0 initiate an automatic remeshing procedure DEFINITION RMSTRK controls the initiation of a remeshing procedure based on the stroke of the primary object. REMARKS There are four keywords that control the initiation of a remeshing procedure (RMDPTH, RMTIME, RMSTEP, RMSTRK) for an object. When the remeshing criteria of any of these keywords has been fulfilled or the mesh becomes unusable (negative Jacobian), the object will be remeshed. RStroke is the stroke increment of the primary object measured from the most recent remeshing. If RStroke = 0, the stroke of the primary object will not be used to determine when the object is remeshed.

RTime is the value of process time allowed to elapses between remeshings of an object. If RTime = 0, the elapsed process time between remeshings will not be used to determine when the object is remeshed. Applicable object types: Plastic, Porous [...]...
