The principal purpose of the *TREAD command is to load data into a table array that is in turn to be used in Ansys commands. The Zeroth column is intended to represent the primary variable TIME if the above Table Array is used in an Ansys command, as indicated by the 6th argument. In the above command, the Table Array’s name will be “my_table”, it is an array of type Table, it is to have 5 rows, 1 column of data (plus a Zeroth column of data), and one plane of data. *TREAD Behavior with 2-Column CSV Files versus Multi-Column CSV FilesĪ Table Array in Ansys is created by the *DIM command, for example: Movement of data from a Table Array into a numerical ARRAY is also illustrated.

This article illustrates use of the *TREAD command, and differences in where data is placed in a Table Array when a 2-column CSV file is read, versus a multi-column CSV file. Users might use *TREAD to enter CSV file data, even if the ultimate use for the data was not in a Table Array.

A CSV file is easily written from an EXCEL spreadsheet, or by other software. 0.123e-2 versus 0.00123), plus, a variety of numbers of digits of accuracy is supported. *TREAD loads data into a Table Array, and is flexible in whether the data is in floating point or exponential format (e.g. The *TREAD command can read data from a Comma Separated Variable (CSV) file, without a format statement. *VREAD loads data into a numerical Array and requires a file with data in a fixed format specified by the format statement. *VREAD, like *VWRITE, requires a format statement to follow immediately. The *VREAD and *TREAD commands read numerical data from an ASCII text file. More complex data structures are possible, but not discussed in this document. The most common data reading needs include numbers from a two-column 2D table, or from a multiple-column 2D table. The *TREAD Command and Comma-Separated Values (CSV)Įngineers using TREAD command in Ansys or the *VREAD command to get data into Ansys Mechanical APDL, sometimes get stuck in the process.
