Table

can store the results of and results from probes, for example. The results are displayed in the window, which by default is located below the window.

If you make any changes to the Table settings, click the button

) at the top of the window.

A node is added under . Click the node to display a table with the selected integration node’s description and values in the window.

You can use Table Graph and Table Surface nodes to plot the data in the tables.

	The Table Window and Tables Node

There are three ways to evaluate a node and put the result in a :

•

Click the button (

) found in the top-left corner of, for example, a window for , , or .

•

In the , right-click the node, and select (

) to evaluate all the nodes. This appends the results to any existing tables. Select (

) to first clear the affected tables and then evaluate all the nodes.

In addition, you can specify the output table for data from a probe in the section of the probe window. Also, for nested parametric sweeps, you can add an accumulated probe table, which provides a matrix of values where the rows and columns represent two independent parameters.

To delete all tables, right-click the main

node and select (

). To clear the contents of all tables, right-click the main

node and select .

If applicable (for accumulated probe tables, for example) select a data format from the list: (the default) or :

	The table itself can be filled regardless of the settings in the Presentation format list.

Filled tables can only be produced by studies that have selected in their parametric sweeps. The filled tables make it possible to retrieve data for a pair of parameters on a matrix format and can be used to make response surface plots, for example. You can get filled tables from some probes or from using derived values when all solutions are selected. Basically, you get filled tables when the input parameters in a parametric sweep (such as time) represent a full outer product. In some cases, such as eigenvalue solutions or if the solver is interrupted, the data is not filled. Also, if you modify the table by, for example, evaluating more than once into the same table or delete columns, the table data is no longer filled.

For a presentation format, under , select a (in addition to the parameter values): , (the default), or . If you select , type the description in the field; that description is then added to the parameter values in the header of each column.

Under , select the parameters to use for the rows and the columns from the and lists, and select the data (probed quantity, for example) to use in the table from the list. These settings are available when the table is filled, also when the presentation format is set to .

Click the button to import data from, for example, a spreadsheet. In the dialog box that opens, select a data file to import. You can import data from text files (*.txt), CSV files (*.csv), and data files (*.dat). If the license includes LiveLink™ for Excel®, you can also import data from a Microsoft Excel® file (some or all of *.xlsx, *.xls, *.xlsb, *.xlsm). The supported Excel file formats depend on whether Excel is installed or not (see Supported Microsoft Excel File Types in the COMSOL Multiphysics Programming Reference Manual).

	The imported data replaces any existing data in the table.

You can import data in multiple nodes to plot exported solution data from different models in the same graph. To do so, after importing the data, create a 1D Plot Group and then add Table Graph nodes that point to each of the tables.

You can also store the table data on file instead of, or in addition to, storing it in the model. Select a way to store the table data from the list:

•

Select to store the table data in the model to a file that you select by first clicking or enter into the field. This makes it possible to, for example, keep track of more data using probes while solving without having to put all the data in the model.

For the storage in the model, specify the buffer size in the field. The default for new tables is taken from the page in the dialog box (factory setting: 10,000 rows). If the table size exceeds that number of rows, the software removes rows from the top. If you use a large number, most table data will fit in the table without being truncated.

	The row limit applies to table data in the model only and not to tables with data stored on a file.

You can specify the headers for each column in the table when the presentation format is set to . In the column, enter the header that you want to use for the corresponding column. When you import table data from a file, COMSOL Multiphysics uses the contents of the last comment row preceding the data to create column headers, which you can edit if desired. For comma-separated data and column headers, the CSV (comma-separated) data file format (.csv files) works best. If a CSV file contains exactly one row without data preceding the data, and the non-data row contains the right number of columns, the import interprets the contents of that row as column headers.

To add a node, if not already created, right-click the (

) node and select . You can also add a table by clicking the button (

), which is in the top-left corner of, for example, a window for , , or . This evaluates the node and stores the result in a new table. This button is also used as the button.
