Dependence on time or coordinates can be specified separately for each type of boundary conditions using tabular and formula dependencies.
Learn more about formulaically specifying dependencies: Dependency from time or coordinates.
Boundary conditions must be preset (Mode - Boundary Conditions).
To set a formula constraint, select a module on the command bar setting the GI dependency (Mode - BC Dependency) and in the appeared form:
select the type of BC;
select an individual component or the entire vector for the application depending on time;
select the type of dependence (the formula can be entered manually to depending on time, you can use standard formulas);
set dependency parameters.
Click Apply.
When using the dependency setting mechanism through tables, it is possible set dependencies on such quantities as:
time;
X coordinate;
Y coordinate;
Z coordinate;
temperature;
frequency;
node;
element;
mode.
When creating a table, you must specify the number of dependencies:
To specify a column name, you must add at least one row, select value in the column and select the name of the desired value in the column on the right.
In this way, you can set complex dependencies on many parameters, For example:
You can also use export and import of tables. For example, like this The table export from the example looks like:
Important: When importing and exporting a file, the column names are not specified! When using the imported table further, you must specify column name through the GUI or using the command:
modify table [ID] dependency [{x | y | z | temperature | frequency | node | element | mode}] column [ID]
A cube made of carbon steel with dimensions 2*2*2 m is given. A load is applied to the volume of the cube in the form of a tabular dependence of temperature on three coordinates from the example above. With static calculation we obtain the following temperature distribution in general form and in cross section:
