Do we support the IBM Power PC chip running Linux?

No, we do not support this platform and do not have any plans to support it in the future.

Q. How to compare the CCL (CFX 5 Command Language) in two different definition or results files?

A. The easiest way to compare them is to use the cfx5dfile command. From the CFX 5 Launcher, go to Tools>Command line.
At the command prompt type in the following:

cfx5dfile file1.def -compare-cmds file2.def

Return. The output will list differences in the CCL. The new and old values are listed. In the following example I am comparing the CCL in a definition and results file:

> cfx5dfile 1390c.def -compare-cmds 1390c_001.res

The output is:

Host Architecture String = <undef> -> intel_p4.sse2_linux2.2.5
Installation Root = <undef> -> /home/CFX/CFX-5.7
Double Precision = <undef> -> Yes
Start Method = <undef> -> Serial
Definition File = <undef> -> 1390c.def
Run Mode = <undef> -> Full
Results Version = <undef> -> 5.7

For a full list of options use "cfx5dfile -help".

You can always use the cfx5cmds command to extract the CCL from a def/res file into a text file and compare them manually.

cfx5cmds -read -def *.def -text *.ccl

I have downloaded and installed CFX-TurboGrid 2.2.1 for Windows XP from the CFX community website. When I try to run it I get a pop-up entitled CFX-TurboGrid 2.2.1 saying:

No license for CFX-TurboGrid could be found
CFX-TG exited with return code 1.

The license service is working fine, all other CFX applications (CFX-BladeGen, CFX-Pre etc) launch with no problems. CFX-TurboGrid 1.6 lauches with no problem using this license file on UNIX

The license file contains the following TurboGrid components

CFX-TURBOGRID-TGG 2.730 1 31-jan-2006 CFDS
CFX-TURBOGRID-TOL 2.730 1 31-jan-2006 CFDS
CFX-TURBOGRID-BOB 2.730 1 31-jan-2006 CFDS
CFX-TURBOGRID-TBG 2.730 1 31-jan-2006 CFDS

The license keys that you have in your license file for CFX-TurboGrid are for version 1.6. To run CFX-TurboGrid 2.2.1 you will need an extra license key called CFX-TURBOGRID-v2.

I'm trying to plot acceleration results from transient dynamic analysis in the time-history postprocessor (/post26). I have issued OUTRES,ALL,ALL but I don't see acceleration available in the GUI and the NSOL command did not accept A as an item even though the manual says it is available. Are acceleration results available for a transient dynamic analysis in /post26?

Yes, acceleration results are available for a transient dynamic analysis in /post26. The OUTRES,ALL command does not include acceleration results. You also need to have OUTRES,A to get nodal...

When I create contact interactively in ANSYS version 8.1 or 9.0 using the Contact Wizard and Contact Manager, upon leaving the Contact Manager, ANSYS unselects all created contact elements. Once contact has been created, and the Finish button has been selected on the Wizard, all elements are selected. But as soon as the Contact Manager is closed, the contact elements are all unselected. What's wrong?

This is a known defect which has been reported (30082)

Below are some important notes regarding the ANSYS and Workbench 9.0 Service Pack 1

The ANSYS 9.0 Service Pack 1 and Workbench 9.0 Service Pack 1, which are now available on the ANSYS Customer Portal, contain extensive changes to several libraries as well as GUI and documentation files. For this reason the Service Packs are being provided as a complete installation, and are larger than normal. Those users who are running both ANSYS and Workbench should install both the Workbench 9.0 ServicePack 1 and the ANSYS 9.0 ServicePack 1.

Please note that the ANSYS and Workbench 9.0 releases must be uninstalled before installing the Service Pack on Windows machines.

A version of ANSYS 9.0 for EM64T Redhat 3.0 Linux is also released as part of the ANSYS Service Pack. This is the first release for this platform. Please note that this version cannot be installed in the same directory as the AMD Opteron 64-bit Linux version of ANSYS.

Do you have an example illustrating a procedure that can be used to account for the bidirectional coupling that exists in a magnetohydrodynamic pump? Eddy currents are induced in the electrically conductive fluid due to both the changing field and velocity effects. The eddy currents alter the field and the associated Lorentz forces move the fluid.

The attached example is a 2D planar model of a pressure driven flow of an electrically conductive fluid passing through a duct. A permanent magnet is positioned over the duct. Velocities from the...
