Option is used to create a boundary region across which material can flow. Set REGION TYPE= EULERIAN to apply the pressure to an Eulerian boundary region. MeshĬonstraints are typically applied on the edge of a sliding boundary region to Meshing will occur along the edge and in the interior of the region. TheĮdge of a sliding boundary region will slide over the material. Set REGION TYPE= SLIDING to apply the pressure load to a sliding boundary region. The edge of a Lagrangian boundary region will follow the material whileĪllowing adaptive meshing along the edge and within the interior of the region. Set REGION TYPE= LAGRANGIAN (default) to apply the pressure to a Lagrangian boundary Will create a boundary region automatically on the surface subjected to the Will move with the material in all directions (they will be nonadaptive). Surface in the interior of an adaptive mesh domain, the nodes on the surface If a distributed pressure load is applied to a This parameter is relevant only for pressure loads applied to the boundary Omitted, the reference velocity is assumed to be zero. Is chosen, the node set must contain exactly one node. The name of a node set containing the reference node. Set this parameter equal to either the node number of the reference node or Pressure loads when the velocity at the reference node is used. It is ignored for all other load labels.Īnalyses and is relevant only for viscous and stagnation body force and The ORIENTATION parameter is valid only for traction and edge load labels TRSHR n, TRSHR, TRSHR nNU, TRSHRNU, TRVEC n, TRVEC, TRVEC nNU, TRVECNU, EDLD n, and EDLD nNU. Used to specify the local coordinates in which components of traction or Set this parameter equal to the name given for the It is ignored for all other load labels.ĭLOADs to remain, with this option modifying existingĭistributed loads or defining additional distributed loads.ĭLOADs applied to the model should be removed. The FOLLOWER parameter is valid only for traction and edge load labels TRVEC n, TRVEC, TRVEC nNU, TRVECNU, EDLD n, and EDLD nNU. Set FOLLOWER= NO if a prescribed traction or edge load is to remain fixed in a Rotate with the surface or shell edge in a large-displacement analysis (live Set FOLLOWER= YES (default) if a prescribed traction or shell-edge load is to Tractions and edge loads (including edge moments) it is ignored for all other The CONSTANT RESULTANT parameter is valid only for uniform and nonuniform surface Moments are to be integrated over the surface in the reference configuration. Set CONSTANT RESULTANT= YES if surface traction vectors, edge traction vectors, or edge Or edge moments are to be integrated over the surface in the current Set CONSTANT RESULTANT= NO (default) if surface traction vectors, edge traction vectors, Quantities such as theĭirection of an applied gravity load and the fluid surface level in hydrostatic Only the load magnitude is changed with time. Amplitude references are passed into user subroutine The step or linearly over the step, depending on the value assigned to the AMPLITUDE parameter on theĪmplitude references are ignored for nonuniform loads given by userĪnalysis. If this parameter is omitted for uniform load types in anĪnalysis, the reference magnitude is applied immediately at the beginning of Variation of the load magnitude during the step. The energy stored in ATP is then used directly or indirectly to drive all other cellular processes that require energy, of which there are four major types: (1) the transport of molecules and ions across cell membranes against concentration gradients, which maintains the internal environment of the cell and produces the membrane potential for the conduction of nerve impulses (2) the contraction of muscle fibers and other fibers producing the motion of cells (3) the synthesis of chemical compounds (4) the synthesis of other high-energy compounds.Set this parameter equal to the name of the amplitude curve that defines the The energy that is derived from the breakdown of carbohydrates, fats, or proteins is used to synthesize ATP. The bond between the phosphate groups in ADP or the two bonds between phosphate groups in ATP are called high-energy bonds, because hydrolysis of a high-energy bond provides a large amount of free energy that can be used to drive other processes that would not otherwise occur. Adenosine can be linked to a chain of one, two, or three phosphate groups to form adenosine monophosphate (AMP), adenosine diphosphate (ADP), or adenosine triphosphate (ATP). Adenosine nucleotides are involved in the energy metabolism of all cells. It is a structural subunit of ribonucleic acid (RNA). a nucleoside composed of the pentose sugar d-ribose and adenine.
