Today, PTC announced that CoCreate 17.0 is planned to be released in Q2.
ANSYS Workbench 12.1 supports CoCreate Modeling 2007 and 2008 (version 16). Version 16.5 should work as well.
Because version 17.0 has not been made available yet, support for CoCreate 17.0 with ANSYS Workbench 12.1 is not known at this time.

In ANSYS, one can define convection from a simple fluid-flow element (FLUID116) to solid or planar elements via thermal surface effect elements (SURF151 and SURF152). The face of the thermal surface effect element is ‘pasted’ on the solid or planar face while the ‘extra node’ is connected with the fluid thermal-pipe element. This [...]

A very useful yet not well-publicized enhancement in Workbench Mechanical 12.1 is the addition of surface-to-surface radiation, which internally uses the Radiosity Solution Method.
I wrote a small tip on how to enable surface-to-surface radiation in Workbench Mechanical (Simulation) a while ago. This tip is now obsolete, as the user can define the radiating surfaces [...]

Many Linux (*nix) commands accept “-r” or similar arguments to recursively process the contents in a directory; a couple of examples are ls -R or gzip -r. There are some commands, however, that do not have such an option — in these cases, xargs is a great way to pass a listing of files [...]

Cygwin 1.7.1 has been released.
Cygwin is a *nix-like environment that runs on Windows. It has its own X server, and it’s indispensable for me, as I often have bash and other scripts that I may wish to run on Windows. You can find pretty much all of your basic Linux tools ported to [...]

Hi everyone,
I’ve the following problem: I’ve a force vs time applied to a fe model. My customer asks me to perform a force spectrum analysis (SVTYP,1). The input for this kind of analysis is a force response spectrum i.e. force vs frequency. my question is: how I can create the FORCE RESPONSE SPECTRUM starting from [...]

Thunderbird 3 is now available for download. The new features are here.
I actually have been using Thunderbird 2 a lot on Windows and Linux, so it’s great to see version 3 finally released. Thunderbird 3 is a little different, but once I got used to the new interface, I’ve started liking it a [...]
