SOLID185 with KEYOPT(2)=3 (for simplified enhanced strain) will not always converge in ANSYS 8.0/8.1 when identical problems using SOLID45 converge successfully. Why? SOLID185 with simplified enhanced strain is supposed to be the same as SOLID45.

This was a bug in ANSYS 8.0 related to different convergence criteria being erroneously set for the SOLID185 with KEYOPT(2)=3.<br>It has been corrected at ANSYS 9.0.

Customer's office is being re-networked from IPv4 to IPv6. Is ANSYS supported on IPv6?

Unfortunately, FLEXlm does not support IP v6 at this time.

I need to do a sequential thermal-stress analysis. My thermal model contains corner noded solids and LINK32 line elements. I am trying to use BFINT to interpret temperature results onto a structural model that has midside noded solids and BEAM3 elements. The temperatures on the LINK32s are not being transferred to the corresponding beams. Is there a way to do this in ANSYS?

Based on the documentation for submodeling, it is apparent that BFINT is not intended to handle temperature data from LINK32, because the submodel technique is documented to apply to shells and...

When I do a nummrg command on keypoints I get the message:

*** WARNING *** CP= 4.026 TIME= 13:36:55
After NUMMRG,KP, node 140923 (and possibly others) is associated with
more than one solid model entity. Future commands which depend on the
node to solid model connectivity (meshing, mesh clearing, solid BC
transfer, etc.) may not operate properly.

Node 140923 is not associated with any of the keypoints that were merged. However, this node is associated with a hard point. Why am I getting this warning?

The HPTCREATE command description documents the limitations on hardpoints. One limitation is that hardpoints are supposed to be created only after the solid model is complete. Doing a NUMMRG,KP...

User gets the following error when using ANS_ADMIN utility to "Configure Connection for Catia V5":

What is causing this error?

This is a random permissions problem on the /CATEnv directory.<br><br>The workaround is to delete the /CATEnv folder in the root of the machine prior to running the configure.

Q. Can I set the density as a function of another variable such as salinity and Temperature.

A. By default, in CFX-5 the user can set an expression for a Material Density to be a function of Pressure, Temperature, and the coordinates (X,Y Z) . This is defined in the RULES file, (see the manual about the RULES file and its location). This may be changed to be a function of other variables, through some simple CCL.

A file den.ccl containing the following information:

# Build Name = Density
# #Allowed Parent List = FLUID TYPE
Description = Material density
Parameter Type = Real
Quantity Type = Density
# Dependency List = p, T, XYZ, pabs
Dependency List = ANY
Solver Name = DENSITY
Lower Bound = 0.0 [kg m^-3]

would allow Material Density to be a function of ANY quantity. The user would include this through the GUI or with the command line
cfx5solve -def 'def file' -ccl den.ccl

Note that for a complex case, eg a compressible mixture, it is important that the overall thermodynamics is self-consistent, or convergence difficulties could occur.

For a multi-component fluid, the density of the mixture is a function of the Material Density of the components, using some form of Mixing Rule. By default, an Ideal Mixture rule is used. See the CFX-5 User Manual for more information. A user could also make the Mixture Density a function of other quantities, eg salinity, by specifying the quantities as Mass Fractions.

I want to print an element plot with element-number on. If print on letter size, the numbering would be overlapped, so I want to print on D-size paper.

I selected PlotCtrs>> HardCopy>>>To Printer>>>HP DesignJet755CM, and specify Paper Size as ANSI D-22"x34" and fit the image to this page. I got a plot in letter size showing on an 11" strip of a 36" wide paper roll.

After some experimentation, it appears that hard copy printing to printer directly from ANSYS canot be done in paper size larger than 11x17. If the requested paper size is bigger than this, say size C, D and E etc, the plot will be on letter size. Redirecting the plot to GRPH file and reading that file via DISPLAY, one can have the image hard-copy-printed on large paper size as requested.

Development was unable to determine why DISPLAY can plot to D size, but ANSYS cannot. Because we do not have a D size plotter to test on, and because the customer has a ready workaround using...


Is it possible to map keys on the keyboard to ANSYS commands to create shortcuts for frequently used commands? I saw something about this previously in #192501.


The procedure has been simplified in recent revisions and you don't need those files. What you need to do is:

1. Create the ANSYS**.KBD file, where ** refers to the ANSYS release. To create the file, add the following command to your start**.ans file for one run only.
Start ANSYS and immediately exit from the program. Remove the above command from the start.ans file or delete the start.ans file.
2. Edit the ANSYS**.KBD file to meet your particular needs.
The demonstration file created in 1 shows how to run various types of ANSYS commands from the keyboard with shortcuts. To see how to do this, add the following command to the file
bind AnsysGUI <F2> [list catch {ans_sendcommand torrus }]
where torrus is a macro file to create a torrus.
3. Use the ANSYS**.KBD file. Start ANSYS. Press the F2 key and watch the results.


Attached to this solution is a sample keyboard file that was created and the torrus macro file.
