ansys.mapdl.core.Mapdl.prnsol#

Mapdl.prnsol(item='', comp='', avg='', datakey='', **kwargs)#

Prints nodal solution results.

Mechanical APDL Command: PRNSOL

Parameters:
itemstr

Label identifying the item. Valid item labels are shown in the table below. Some items also require a component label.

compstr

Component of the item (if required). Valid component labels are shown in the table below. Default = COMP.

avgstr

Specifies whether random acoustic results are averaged. Valid only for Item = U and PRES.

  • (blank) - No averaging (default).

  • AVG - Print averaged results for random acoustics.

datakeystr

Key to specify which data is printed:

  • AUTO - Nodal-averaged results are used if available; otherwise, the element-based data is used, if available. (Default.)

  • ESOL - Only element-based results are used. If they are not available, the command is ignored.

  • NAR - Only nodal-averaged results are used. If they are not available, the command is ignored.

Notes

Prints the nodal solution results for the selected nodes in the sorted sequence. For reinforcing elements (REINF nnn ), results are printed at intersection points of reinforcing elements and base elements.

For example, prnsol,U,X prints the X component of displacement vector U (that is, the UX degree of freedom).

Component results are in the global Cartesian coordinate directions unless transformed ( rsys ).

Various element results also depend upon the recalculation method and the selected results location ( avprin, rsys, layer, shell, and nsel ).

If layer is issued, the resulting output is listed in full graphics mode ( graphics,FULL).

You can define which component of the nodal load (static, damping, inertia, or total) should be used ( force ).

PowerGraphics can affect your nodal solution listings. For PowerGraphics ( graphics,POWER), results are listed for the model exterior surfaces only.

When shell element types are present, results are output on a surface-by-surface basis. For shell elements (such as SHELL181 or SHELL281 ), and for ELBOW290, printed output is for both the top and bottom surfaces. For solid elements such as SOLID185, the output is averaged for each surface and printed as follows:

  • Node at a vertex: Three lines are output (one printed line for each surface).

  • Node on an edge: Two lines are output (one printed line for each surface).

  • Nodes on a face: One value is output.

  • Nodes interior to the volume: No printed values are output.

If a node is common to more than one element, or if a geometric discontinuity exists, several conflicting listings may result. For example, a corner node incorporating results from solid elements and shell elements could yield as many as nine different results; the printed output would be averages at the top and bottom for the three shell surfaces plus averages at the three surfaces for the solid, for a total of nine lines of output. The program does not average result listings across geometric discontinuities when shell element types are present. It is important to analyze the listings at discontinuities to ascertain the significance of each set of data.

When only reinforcing elements (REINF nnn ) are selected, results are listed for intersection points of reinforcing elements and base elements. Prints include coordinates of intersection points in global Cartesian coordinate system and results. Results are interpolated from the results of base elements. If a point is common to more than one reinforcing element, or reinforcing member within one reinforcing element, averaged results are printed. Prints also include minimum and maximum values.

The printed output for full graphics ( graphics,FULL) averages results at the node. For shell elements, the default for display is TOP so that the results for the top of the shell are averaged with the other elements attached to that node.

If nsort, esort or eshape is issued with PowerGraphics enabled ( graphics,POWER), prnsol behaves as though full graphics mode is enabled ( graphics,FULL).

Items not supported by PowerGraphics are noted in PRNSOL - General Result Item and Component Labels.

For Item = SRES, selected result component ( osresult ) values are output. See PRNSOL - Selected Result Component Labels.

To print midside nodes, first issue efacet,2.

To learn more about the specific behaviors of prnsol in a cyclic symmetry analysis and printing results for nodes at cyclic edges, see Using the /CYCEXPAND Command

If nodal-averaged results ( outres,NAR or another nodal-averaged label) are in the database, then prnsol uses the nodal-averaged data for the applicable items (S, EPEL, EPPL, EPCR, EPTH, EPSW) by default. You can change this behavior via the DataKey argument. Keep these points in mind when using nodal- averaged results:

  • The layer and rsys,SOLU commands are not valid with nodal-averaged results. If these commands are used, the element solution is printed instead if applicable.

  • Issuing esel before printing nodal-averaged results has no effect on the output.

  • PowerGraphics is supported. The output is equivalent to the full model graphics output, but only the appropriate surface nodes are printed. See Postprocessing Nodal-Averaged Results
