CFD Tools
CFD Toolbar:

To make it user friendly for first time CFD analysts µETA provides with a built-in CFD Toolbar. This toolbar efficiently bring together the different  functionalities in µETA usefult for CFD result analysis under one window to help faster post processing.  Functions such as loading of files, calculation of Drag/Lift Forces, calculation of Drag/Lift Coefficients, generation of time series 2D plots and contour plot creation can now be done using this toolbar. The help section is well documented for user assist.

New toolbars can be created to provide user with a custom post - processing interface. These toolbar can either be analysis - oriented or just an individual's frequently used commands. These toolbars can be define within µETA using the Toolbar Designer or inside the META_post.defaults file using any text editor. This greatly enhances the efficiency of post - processing by providing a "One interface for all" environment to the user. These toolbar can be saved and shared between users or groups involved in similar operations.


Streamlines

µETA provides an efficient way to create and manage streamlines for CFD analysis. The user has the choice of creating ribbons or cylindrical streamlines with user defined twists. These streamlines can be edited interactively with controls to modulate them based on result sets. µETA can also use these streamlines to visualize Oil Flow paths on user selected parts of the model.


Video & Image Synchronization

µETA allows the user to match the test video and the animation from the model to compare the CFD analysis and wind tunnel test data. This tool can be applied in many areas. For example, a smoke simulation test video from wind tunnel testing can be compared with that of the CFD simulation model to get an estimate of correlation. The user can also track a point on the video and plot the results on a 2D plot from the same window.


Multi Model Post Processing

µETA brings a unique functionality to post process & compare multiple models for CFD simulation results. The user has capability to read model results from different solver datasets. Tools such as part statistics includes detailed information regarding the selected model and the current state. The user can filter and focus on specific PIDs which, for example, may experience high fluid flow pressures. Multi model state statistics is a table displaying information on Maximum and Minimum values of results at All entities (Parts, Nodes, Elements and Groups) level, for every state, and for every available model. User can also create and compare contours and Vector plots for more than one models in the same µETA session.

Both recording tables comprise comprehensive, completely configurable, spreadsheets, for all available results of models, offering the option to save data in HTML and CSV format.


Fringe plots, Range & Colors

µETA offers the ability to draw fringes for a particular load case to visualize the pressure, velocity, Wall turbulence etc. The fringe can be applied on nodes as well as elements and the user can draw a normal plot, contour or vector plots. The fringe range can be automatically calculated or can be supplied by the user. µETA also allows the fringe to be non-linear. The fringe colors can be changed by the user very easily by changing the color settings. The user can add/remove colors from the fringe bar or invert the colors altogether to visualize the results like fatigue life, which requires inverse color order.


Cut Planes

Cut planes are very useful during post-processing. For example, the user can cut the important sections and visualize the animation or fringe very close to the section. µETA offers the functionality to cut sections very easily. Once the section is cut, the user can edit the section to move it to place it exactly on the area of interest. If the cut planes are defined in the input deck, they can read into µETA during geometry/results input. Cut planes can be isolated using the focus group like any other entities in µETA. When a µETA project file is saved, the cut planes are automatically saved and can be retrieved when the project file is opened again.


Iso-Surfaces

Iso-function is a feature that provides visibility of areas (“contour areas”) of the model of the same value regarding either node or element data. Iso functions can be used to visualize how the load/stress is flowing thru a component. µETA offers the ability to create Iso-functions easily with one click.


Report Composer:

µETA offers a Report Composer tool to facilitate fast and effortless communication of results across departments. Reports are readily generated based on interactively built templates. The report can be generated in either HTML or PPTX format and the composer supports texts, tables, images, embedded objects and links. The concept of the Report Composer is to create the templates once and then set up the report interactively. Once this is accomplished then the user can save the created session file and run this session every time a report needs to be created.
