ANSOL, NVAR, NODE, Item, Comp, Name, Mat, Real, Ename
Specifies averaged nodal data to be stored from the results
file in the solution coordinate system.
NVARArbitrary reference number assigned to this variable (2 to NV
[NUMVAR]). Overwrites any existing results for this
variable.
NODENode number for which data are to be stored.
ItemLabel identifying the item. General item labels are shown in Table 116: ANSOL - General Item and Component Labels below. Some items also require a component label.
CompComponent of the item (if required). General component labels are shown in Table 116: ANSOL - General Item and Component Labels below.
Name32-character name to identify the item on the printout and displays. Default: An
eight-character label formed by concatenating the first four characters of the
Item and Comp labels.
MatMaterial number. Average is calculated based on the subset of elements with the specified
material number. Default: Use all elements in the active set unless
Real and/or Ename is specified.
RealReal number. Average is calculated based on the subset of elements with the specified real
number. Default: Use all elements in the active set unless
Mat and/or Ename is specified.
EnameElement type name. Average is calculated based on the subset of elements with the specified
element type name. Default: Use all elements in the active set unless
Mat and/or Real is specified.
Valid item and component labels for averaged nodal results are listed in Table 116: ANSOL - General Item and Component Labels.
All element nodal quantities are obtained in RSYS, Solu and then averaged.
ANSOL defines averaged nodal results data to be stored from a results file (FILE). Not all items are valid for all nodes. See the input and output summary tables of each element attached to the node for the available items.
Coordinate systems:: All element nodal results used by ANSOL for averaging are in the element coordinate system, except for layered elements. Layered element results are in the layer coordinate system. You can further specify the element nodal results, for some elements, with the SHELL, LAYERP26, and FORCE commands.
ANSOL does not transform results from RSYS,SOLU to other coordinate systems. Verify that all elements attached to the subject node have the same coordinate system before using ANSOL.
Shell elements: The default shell element coordinate system is based on node ordering. For shell elements the adjacent elements could have a different RSYS,SOLU, making the resultant averaged data inconsistent. A message to this effect is issued when ANSOL is used in models containing shell elements. Ensure that consistent coordinate systems are active for all associated elements used by the ANSOL command.
Dervived quantities: Some of the result items supported by ANSOL (Table 116: ANSOL - General Item and Component Labels) are derived from the component quantities. Issue AVPRIN to specify the principal and vector sum quantity averaging methods.
Default: If Mat, Real
, and Ename are not specified, all elements attached
to the node are considered. When a material ID, real constant ID, or element-type
discontinuity is detected at a node, a message is issued. For example, in a FSI analysis, a
FLUID30 element at the structure interface would be considered;
however, because it contains no SX result, it is not used
during STORE operations.
