To change the format of numbers displayed next to the colormaps go to<br>Display->Colormaps.<br><br>In the Colormaps panel one can select the desired number format type.

KR102: How can I locate and fix left handed cells?


1. The left-handed faces mostly occur at locations where the surfaces that are non-conformally connected have sharp corners or contortions. When you get the left-handed faces, you can fix it...

KR103: How can I locate cells with low temperature?


Following is the procedure to locate the cells with low temperature:<br><br>1)Read the case and data in which temperature limitation messages were coming.<br>2)Open the Adapt...

KR104: How can I suppress the warning messages about reversed flow at certain boundaries or regarding limits on certain variables such as temperature or turbulent viscosity?


These warning messages could indicate potential errors or inconsistencies in your problem definition within FLUENT. In other cases, they may appear only during the early convergence stages of your...

KR105: Error: divergence detected in AMG solver: pressure correction---what does this mean and how do I fix the problem?


This error message is an indication that the ¿pressure correction¿ equation is diverging. The most likely cause is that the under-relaxation factor (URF) for that equation is too...

KR106: How do I resolve the following error:
Error: > (greater-than): invalid argument [2]: wrong type [not a number]
Error Object: nan


This error occurs when FLUENT gets information from the Cortex (GUI). FLUENT is expecting to get the data in a specific format, but gets another. This generally occurs when FLUENT attempts to...

KR107: How can I identify zone names and display them?


Go to Surface-> Zone. Select the zones you want to identify one by one and press `Create¿.<br><br>These zones will now appear as surfaces in the Display->Mesh...

KR108: How to resolve warning message saying the turbulent viscosity limited to viscosity ratio?


Also review Siebel Solution 2002233.<br><br>The message you are seeing is more a warning than an error. It stipulates that the ratio of turbulent viscosity over the laminar viscosity...

KR109: How can I save my contour plot settings?


For frequently used combinations of contour variables and options, you can store the information needed to generate the contour plot by specifying a Setup number and setting up the desired...

KR110: How to resolve warning message involving the temperature limits?


There are two main causes for this: shell conduction initialization and reacting flow/heat transfer issues.<br><br>If you are using Shell conduction, you must patch the shell zones...

KR111: When using planar conduction, which temperatures should be displayed on the boundary walls?


When one is using planar conduction (sometimes called in-plane conduction or shell-element conduction) to account for both in-plane and normal heat conduction on boundary walls, you need to be...

KR112: How do I resolve the following error: FLUENT received fatal signal (ACCESS_VIOLATION)?


This is the standard error caused by FLUENT trying to access data that has not been allocated.<br><br>There are several causes which we will discuss.<br><br>For example, in...

KR113: How to plot data on a circular surface?


Fluent has the option of creating a circular surface to plot data.<br><br>Surface -> Quadric.<br>Type: Circle<br>Specify origin and radius and it creates a circle...

KR114: How to record the animation showing at Sweep Surface


There is no straightforward way of doing this with Fluent.<br><br>It may be done with scheme commands to export *.tif files at various surfaces. This may take some...

KR115: How do I find specific geometry information from the case file for a specific zone (like xmin, xmax, ymin, ymax etc)?


Following are the steps to get domain extent of a particular zone:<br><br>1. Initialize the case<br><br>2. Go to Surface->Iso-Surface<br><br> - Select...

KR116: How to Repair Rotationally Periodic Zones in FLUENT?


For cases with periodic boundary conditions, the minimum, maximum, average, and prescribed periodic angles are computed and reported when you perform Grid /Check. Many times the reported average...

KR117: Why is the mass flow rate of a chemical species into the domain not equal to the product of the mass fraction and the bulk mass flow rate?


The net mass flow rate of a species at an inlet boundary includes contributions from both convection and diffusion. The convection component is determined from your input of species concentration...

KR118: Warning: materials in neighbor cell threads (3 and 2) of interior zone 19 are of different types (aluminum and water-liquid). This problem MUST be fixed before solving!


In FLUENT, a Wall/Wall-shadow pair must separate solid/fluid regions. Between fluid/fluid regions, we can have an INTERIOR zone type.<br><br>It is also possible to convert a solid...

KR119: Can I read in 6.3 files in 6.2?


I created a case file with Version 6.3, and then read it into version 6.2 on a different computer. Now I always get the following error messages everytime I write or read in the case...

KR120: How can I assign current time as flow time for a transient problem?


I am doing unsteady flow simulations. There are a number of processes involved in a complete cycle: reaction, regeneration and reduction.<br><br>I have created individual case for each...

KR122: Access MRF parameters using UDF's


While using MRF model in Fluent, user can only specify constant values of angular velocity for fluid and wall zones using GUI.<br><br>Also, Fluent GUI does not have any direct hooks...
