TSV-Post

Support for large models

TSV-Post can handle models including multimillion nodes with a single PC (Pentium 4 class) and its performance will not frustrate its users.
TSV-Post can display models of 10 million DOFs in only 1-2 seconds, provided that the file is converted into its original vns format. Data extraction, sorting, grouping, and processing can be performed easily even for such large models. This was realized by the data structure called “FROVI” (Fully Relational Object Visualization Integrator) , which was developed originally by TechnoStar.

 

 

3D mouse

The 3D mouse was originally developed by TechnoStar and can display all parts of the model at the user’s will. Now any information , for example the inner geometry of the structure, or the results, can be observed as you wish.

 

Data extraction and processing

Data can be extracted from any part of the displayed model by various picking methods (by node, element, arbitrary point, specified area).
Various graphs can be displayed, such as the X-Y plot or edge distribution.

The extracted data can be easily processed into the data needed by the designer by predefined library functions or user defined functions.

Transient phenomena

Realtime data can be extracted from a model while displaying its transient phenomenon, and displayed in an X-Y plot.

 

Grouping / Sorting

Even a 10 million DOF model can be sorted or grouped instantaneously by the ultrahigh-speed operation algorithm of TSV-Post.
The model and results are grouped according to specified IDs, element type, material type, or multi-cutting.
Of course, sorting can also be performed within the groups.

MDI function

MDI (Multiple Document Interface) is a useful function that can simutaneously display multiple models, or a single model with different results data on the same screen.

 

Macro function

The macro function can compare two or more results on the same screen.
Because a record of the user’s operation is saved, it is easy to compare the results of two models with partially different geometries, or two models with the same geometry but different boundary conditions.

 

Frequency response function

The frequency responce function is supported in TSV-Post.This function calculates the input frequency response from the normal mode analysis results obtained from solvers such as Nastran.This corresponds to the modal frequency response analysis function in Nastran (SOL 111).
Once the normal mode data is saved, they can be combined within TSV-Post in order to perform frequency response analysis, so there is no need to return to the solver.
Because the extra fast database of TSV-Post is used, the displacement, velocity, and acceleration responses of the specified nodes can be calculated instantaneously, even for models of 1 to 2 million nodes.
Input nodes and response nodes can be picked from the GUI while displaying the calculated results, which is very convenient as well as efficient.
The calculated results can be displayed as an XY graph for comparison. Also, the Windows environment allows the user to transfer data to Office applications such as Excel or Word using the clipboard, which provides efficiency for generating reports.

Fluid-structure mapping

One of the key features of TSV-Post is its high performance due to the innovative data structure. The fluid-structure coupling function clearly proves the high performace of TSV-Post.

img_merit03_01Results from fluid analysis such as the film coefficient, fluid pressure, temperature distribution is often used in structural analysis as input data. In such cases, the fluid and structural analysis models usually have different meshes. In order to use the fluid analysis results in structural analysis, the data between the two different meshes need to be converted.

Conventional software applications required an immense amount of time to search for the boundary surface between the fluid and structural models. TSV-Post can convert the data of a regular sized model (for example from a fluid mesh of 5 million nodes to a structual mesh of 500,000 nodes) in less than one minute, due to its unique data structure. The same can be said for mapping from electromagnetic analysis to structural analysis.

Strain gauge

The strength of the strain gauge is often analyzed in order to assure product safety and simulation accuracy.
TSV-Post can automatically calculate and display the average value of strain gauges with different sizes. The average value can be obtained not only for principal stress (default) but also for a given direction. Also, the strain stress of an arbitrary point in the given direction can be calculated.

FFT function (Fourier transform of bore deformation)

The FFT function (Fourier transform of bore deformation) is supported in TSV-Post.For example, the bore deformation of an engine cylinder block can be expanded easily into Fourier series, to measure the deformation of each order.

Operation can be done very easyly via the GUI, and the automatic interpolation functions provides measure points even if nodes do not exist.

The circularity calculated from each order and its summation is displayed in a graph as shown below.
The sum of the circularity can be calculated practically by eliminating simple expansion or simple moving such as mode 0 or mode 1.

  1. Obtaining data

TSV-Post allows you to easily obtain Post data.

You can obtain data of arbitrary points as well as nodes and elements, also by entering the specification ID.

Images can be captured and exported to PowerPoint, which can be very useful for generating reports.The obtained data can be saved in CSV format.

  1. Using the 3D mouse during animation display

TSV-Post provides the 3D mouse feature, which can be used to obtain information on the cross section area. Since the 3D mouse can be used during animation display, the deformation of the geometry can be confirmed for an arbitrary cross section.
