Using universal files in post-processing

You can view results from universal files in post-processing. Universal files are an NX I-deas file format that you can use to store and transfer information, such as results.

• An ASCII universal file (.unv) is an ASCII sequential data file. ASCII universal files are human readable and can be viewed or edited in a text editor.

• A binary universal file (.bun) uses the same format as the ASCII universal file but the data written in binary format.

Contents of universal file datasets

A universal file is comprised of blocks of information called datasets. Each block begins with a dataset delimiter line that contains -1. This minus sign is in column 5 and the 1 is in column 6. The remainder of the line is blank. Each dataset begins with a delimiter and ends with a delimiter. Between datasets, the file can contain lines, such as comments, which are not part of any dataset.

ASCII universal file format for post-processing

Post-processing requires that a universal file contain the following datasets:

• 164 – Units (optional)

• 2411 – Nodes

• 2412 – Elements

• 2414 – Results

• 2420 – Coordinate Systems (optional)

The units and coordinate system datasets are optional. If a universal file contains the units dataset, post-processing can infer the correct units when attaching the results file.

A typical universal file to be consumed in post-processing has a nodes dataset (2411), an elements dataset (2412) and one or more results datasets (2414). A 2414 dataset is created for each type of result you want to place in the file, for example, displacement, stress, and so on.

Note:

You can also create a companion result file using the universal file results. If you do, note the following:

• Datasets 2411 (nodes) and 2412 (elements) are not included in the universal file. The software recovers the node and element data from a parent result file, which must be defined. The software assumes the companion result file originated from the parent file, and, therefore, has the node and element geometry that matches the parent results. For a companion result file, your universal result file only needs to contain dataset 2414 (analysis data).

• Dataset 2435 (permanent groups) is not supported in post-processing.

• Dataset 164 (units) is not included in the universal result file. Therefore, the units used for the companion result file are those of the system or the parent result file.

Binary universal file format for post-processing

The software also supports a binary universal file format. A binary universal file (.bun) uses the same format as the ASCII universal file but the data written in binary format.
