I would like to be able to measure distances within Study environment.

Like in a CAD or Mechanical

Exclusive licence for meshing and solving

Status: Under Review
by *Expert Elite* on ‎06-04-2013 01:40 AM



It is puzzling that while we are meshing, we have to give away a licence in solving, forcing us to stop the jobs running in the queue, just to be able to mesh. In most commercial CFD (or FEA) software packages that I know of, I see that meshing and solving are completely exclusive of each otherin a single licence.


Majority of time of every CFD engineer is occuppied in meshing at his workstation. At the same time, he can't finish his job unless these meshes are run, often in the remote cluster etc. Sorry if I sound rude, but is it me, or has Autodeksk really employed this unfair and unjust tactic to engage a solver licence in meshing, thereby indirectly forcing users to go for additional solver licences, so that they can continue both meshing and solving uninterrupted at the same time?


I know this may call for a major overhaul in code (or maybe not), but is it not reasonable to demand that  "meshing" and "solving" be treated exclusive of each other?

Operative Temperature

Status: Under Review
by huijin9055 on ‎04-03-2014 09:30 AM

According to ASHRAE standard 55, human thermal comfort is defined by a range of operative temperatures, which is a combination of air temperature and mean radiant temperature. Only under certain circumstances, it is acceptable to assume operative temperature is equal to air temperature. For example, when there is no radiant heating or cooling systems. I notice Simulation CFD does not report operative temperature in the result, not sure if it is calculated in the solver. We're hoping that operative temperature will be available in a future release.

Progress bar

Status: Under Review
by Contributor RobTipples on ‎08-12-2013 06:45 AM

Could some sort of progress bar be implimented? Ideally this would consist of 2 parts:

1) Something that says that autodesk is still working such as the spinning symbols that other software uses

2) A progress bar estimating how long is left/how many more tasks must be done before completion

show/hide in setup phase from panel bar

Please add the show/hide functionality for volumes in the browser when in the setup phases. With ctrl/shift select as well.


This would be useful when trying to hide volumes that are very small and can't easily be selected in the graphics interface.

There's  been numerous occasions where simulation of water evaporations is needed. One example would be to simulate the water loss (through evaporation) for a heated processing chamber. The processing chamber processes sludge and liquid waste materials by heating it and extracting the water content. 


The current CFD module for condensation is limited and it cannot fully capture water vapors moving in control volumes.


For an illustration, refer to the link below (under process flow):



The evaporation process happens in the heated Process Chamber.

Heat Pipe Compact Model for CFD

Status: Under Review
by xsipower on ‎05-17-2013 02:09 PM

Heat pipes are quite ubiquitous these days in electronic packaging. The short cut to model the heat pipe as a highly conductive (~50-100,000 W/mK) rod must be done very carefully as it does not take into account the heat transfer capacity based on temperature and tube diameter. If the one does not take into account these variables then the simulation will give extremely optimistic results.


It would be great if Simulation CFD had a Compact Material Model for heat pipes that would perform the necessary transfer curve for the model.

Mesh Options

Status: Under Review
by Contributor matthew.brown on ‎01-15-2013 09:30 AM

Fix the mesher!  I would gladly pay more a software package that was capable of decent grid generation.  Either that or implement a mesh import option so users could use 3rd party software to generate a usable mesh.

Mesh Adaptation for 2D Analysis

Status: Under Review
by Product Support Royce_adsk on ‎01-29-2013 10:16 AM

When doing 2D compressible analysis that include shocks, having adaptation would produce a more efficient and sharper result.  Would also be a good test bed to test adaptation strategies before running a larger 3D model.
