MixSim: How to use "Profile Baffles" in MixSim2
|
In the MixSim User's Guide, there is no information about the structure of ".mxo" (MixSim Object) files for adding profile baffles (and other user-specified) objects. This answer will not explain MixSim Object files (.mxo files) in general -- it will only explain how to use the "Profile Baffles" sample file: 1.: Find the file ".../Fluent.Inc/mixsim2.0/Mixsim-Object-Library/SampleProfileBaffles.mxo" 2.: Create a copy of that file (in any location of your choice!) and give it a different name(!!) 3.: Open the file with a text editor that doesn't add any formatting information (like "notepad" in Windows or "VI" on Linux). 4.: In the fourth line, change the "Name" field value from "Sample Profile Baffle" to anything other unique. 5.: In the long list between "[Parameter List]" and "[End Parameter List]", find the parameters that define the geometry and cannot be modified through the MixSim GUI (!), and modify them adequately: These are " XCoordinates" and "YCoordinate". In these two parameters, which are both of parameter type "Profile", set the "Number Of Data Points" value to the same value (which is the number of vertices that describe the baffle geometry), and set the X coordinate values and Y coordinate values for all vertices in the same order. Try to understand the default file by viewing the "X Coordinates" and "Y Coordinates" value lists and comparing these data to the geometry that is displayed by MixSim. In the sample file, the ordering of the vertices starts with the lowest vertex on the *inner* baffle edge, i.e. the bottom baffle corner that faces *away* from the tank wall. The ordering continues then upward along the "inner" edge, around the baffle top end, downwards along the "outer" baffle edge (facing towards the tank wall), and finally inward again to meet the start point (which is NOT repeated -- the loop is closed automatically by MixSim). 6.: Save the modified file. If it is not saved in the standard location under the MixSim installation directory (.../Fluent.Inc/mixsim2.0/Mixsim-Object-Library), please set the "User Object Library Directory" to the correct directory in MixSim *before* you create a new model to use the new baffle object. (cf. Solution no. 911 for some more details about the use of the "User Object Directory".) 7.: Please note that it will probably not be possible to add the new baffle type to an existing model without any problem. The Release Notes document contains some hints to make it easier for you to transfer as much information as possible from an old model to a new one. |
