How to model negative heat flux BC on water tubes in a furnace |
a furnace is modeled using pdf gas combustion. In reality, water tubes run along the walls of the furnace carrying water. One may be inclined to not model the internal tube walls but assume the... |
FLUENT 6 - How to change the MRF fluid zone rotational speed with time? |
It is desired to run a rotating case (SRF, MRF) and ramp up the rotational speed as a function of the iteration number (or flow time for an unsteady case) in order to get better convergence. ... |
How to specify time varying wall velocity ? |
User wants to run an unsteady case and specify a time-varying velocity to the<br>wall. The case corresponds to an aircraft that is slowing down on the runway.<br>The incoming velocity... |
Turbulence viscosity needs update when realizable k-e model is used for volume fraction related calculation |
After reading cas/dat files and doing the first iteration, the message would always appear:<br>turbulence viscosity limited to viscosity ratio of 1e05<br>, though it didn't... |
Adjusting massflow-inlet boundary to achieve a target thrust |
For external aero applications involving the modeling of a full aircraft with<br>engine and pylon, client typically knows the massflow rate incoming to the<br>engine fan inlet and also... |
How to check if right volume source is being applied to a fluid zone? |
A linearly varying energy source term is to be applied to a fluid zone. In order to make sure the total source term is correct, the function has to be integrated over the fluid... |
Mixsim2: Windows: Cannot use ACIS CAD file for impeller definition -- Gambit doesn't find the file |
I'm trying to define an impeller using my own ACIS (.sat) CAD file through the "Custom by ACIS file" impeller object. But when the Gambit process inside MixSim is supposed to... |
Mixsim2: Windows: Cannot write compressed case and data files (.cas.gz, .dat.gz), gzip process fails |
In one test of the whole production test matrix, MixSim2.0 failed to write compressed (gzip, .gz) case and data files after it had already worked once before within the same... |
Mixsim2: Manipulating (rotating) preview graphics: cortex receives SIGSEGV |
I look at the preview graphics and rotate it vigorously. After a few seconds, cortex receives a "fatal signal (SEGMENTATION VIOLATION)". This can be reproduced on both Linux and... |
How to stretch/scale one dimension (not all three) in FIPOST? |
I have a model in which the thickness is much, much less than the width and length.<br>Is there a way to only scale the thickness, say increase it by 10x, during FIPOST so that I can... |
How to increase FIPOST memory for plots? |
When I run a large number of iterations (say, 12000) and then go to make a<br>convergence plot in FIPOST, I get a message stating I have insufficient memory for the<br>operation. How... |
POLYFLOW - Performances of UDF versus PMAT functions |
POLYFLOW simulations involving UDF are usually computationally more expensive than without UDF. In order to reduce the required calculation time, UDF are evaluated only once per element by... |

Mixsim 2: Post-processing trouble in MixSim AND when switching to FLUENT, and in FLUENT 6 stand-alone when re-reading in the case and data file:<br><br>I set-up a vessel with a... |
Mixsim2: impeller surfaces generated at mistaken location |
MixSim 2 can create surfaces around impellers automatically using the menu item "Postprocessing---Impeller-Surfaces".<br>Sometimes, some time after their creation, and after... |
Mixsim2: Shaft tip not meshed properly, or meshing of impeller compartment fails completely |
The shaft tip is relatively neat an impeller.<br>When meshing the configuration, the shaft tip is not meshed properly (as can be seen in the Grid Display), or meshing the impeller... |
Gambit - Can I reduce/enlarge the font size in the text console of Gambit 2? |
It is not possible to change only the text console font size in Gambit.<br><br>However, the font size option can be used to control all the fonts in the Gambit... |
Field View Export for Relative velocity vectors: |
How to view vectors of relative velocity inside the Field view, using the data exported from FLUENT ? FLUENT does not export relative velocity as a vector form for field view export. Following is... |
Mixsim2: Correlations panel is empty (no values, no impellers listed) -- Error message "invalid function". |
In Mixsim 2.0.2, I try to open the pre-CFD correlations panel by the menu item "Report---Correlations".<br>The panel comes up, but it doesn't display any values in the... |
