Tables are one possibility, besides formulas, that allow to specify a variable (velocity, temperature, etc) along with another independent variable ( e.g time or distance).
Not every variable is allowed to be defined as a function of another variable. If tables are allowed, you can find the icon of a graph next to the variable you want to define.
Once you click on the 
icon, a dialogue box appears to define the table. The example below shows a table input for a time dependent temperature boundary condition. The data can be uploaded in CSV format or dynamically manipulated at the interface.
The CSV file should just contain the input values (no title, index numbers…). Every line in the text file will define a row and values separated by a comma ‘,’ will define the columns. As an easy example, the CSV file for the table seen above should be like the following:
0,300
1,320
Once the CSV file is uploaded, the variable for each column should be properly set. Values can be manually modified and rows/columns can be added/deleted by right-clicking on any cell. The data from the table can always be downloaded pressing the icon next to ‘Browse files’.
Under Advanced settings, two different options appear.
Important
For Code Aster based solvers you can as well specify the interpolation and the extrapolation type between the given value pairs:
For ‘Vector’ variables (e.g velocity) the table upload requires a CSV file with the independent variable and all 3 velocity components in the order X, Y, and Z for each point. Depending on the independent variable we can find two different types of table:
The following are some of our tutorials where you can try using the tables feature:
