The ANSYS 10.0 interface to FiberSIM does not appear to give the correct
results. Is the composite material data being handled correctly? |
No, Defects 51425 and 51487 were filed to correct the data format.<br><br> Defect 51425 dealt mostly with graphical displays showing the wrong<br> layer orientations. ... |
Is ICEM CFD 10.0 certified to run on SuSE 10.0? |
Although SuSE 10.0 was not tested, ICEM 10.0 should run on it.<br>However, we can not guarantee there will be no problems.

How do you set up a subdomain for a source that grows in size? |
<br>Subdomains do not normally change size but it is possible to set a subdomain to be the whole domain and use a CEL expression to define the source volume. For example the following... |
How can you get good convergence when simulating heat transfer in a closed room? |
<br>Closed rooms have no outlets or openings so there is no boundary for the solver to use as a pressure reference region.<br>In addition, if there is heat transfer into the room it... |
How can you set up a heat source in CFX 10.0 in a subdomain that results in a constant temperature in that subdomain? |
<br><br>You can set a CEL expression for the heat source such as:<br>HeatIn = HCoef * (Treq - T)<br><br>where Treq is the required temperature and HCoef is a positive... |
I did not create a monitor point at the start of the simulation. How can I now extract monitor point information from a results file? |
<br>The easiest way to get the time history of a monitor point is to set up a monitor point in CFX-Pre. The solver will then output the monitor point information for every time... |
Class 3 Error
SYMPTOM:
In spray simulations, the spray penetration depth strongly depends on an integration parameter for the particle solver ('Number of Integration Steps per Element'). This dependence is related to the physical process itself, and the time scales of this process need to be resolved accurately in order to eliminate the dependence.
PROBLEM:
The strong dependence is caused by an incorrect time step, passed down to the droplet break-up routines in th |
WORKAROUND:<br>No workaround is currently available.<br><br>FIXED IN:<br>Release 11.0.

Will RSM 10.0 and RSM 11.0 work on the same web server? |
RSM 11.0 has no web service.<br><br>You can use the same RSM 10.0 web server as the RSM 11.0 manager machine.<br><br>RSM 10.0 and RSM 11.0 should co-exist with no problem.

Q:
I have a 2 PCs each running Windows. I'm trying to set up a distributed parallel calculation using these 2 machines, the CFX 10 solver and MPICH.
I have installed rsh and MPICH on both machines and have registered a user who has access to them both, following the instructions in the ANSYS CFX Products Installation and Configuration Guide, pages 35 - 45.
However when I run the MPICH distributed parallel solver I get the following error in the solver output file:

A db file that contains defeatured model geometry and was created on any Unix platform
does not properly transfer to a Windows 32-bit PC. It either aborts during the resume or the
solid model data is totally corrupted. What causes this behavior? |

Check the voltage or current you applied to the TEC. This is one of those times where more power makes things worse. Reduce the voltage or current and try running it again.
