Initial Conditions

In Fidesys, initial conditions can be defined for any geometric objects and node sets. The following types of initial conditions are acceptable: displacement, velocity (including angular) and temperature. In case of export in the Abaqus program, it is also possible to set acceleration and generating fields as initial conditions.

To create initial conditions within the graphical user interface should:

On the Command Bar, select Mode - Initial Conditions.
Select the necessary initial condition: Displacement, Velocity, Angular velocity, Temperature, Pore pressure.
In the group of radio buttons Action select Create.
Using the dialog elements, specify the objects for which the initial condition is determined, and enter the characteristic its meaning.
Click Apply.

In the command line window, you can create initial conditions as follows:

create initial {displacement|velocity|angularvelocity|temperature|porepressure} on {volume|surface|curve|vertex|node|nodeset} [all] <ID>

For most types of initial conditions, only two are required parameters: a set of nodes and a value considered as initial. As an option, the name of the initial conditions is possible.

To change the initial conditions using the graphical user interface in the group of radio buttons Action (step 3, see above) follows select Modify. When using the command language it is necessary to replace the keyword create with modify in the above commands, for example:

modify initial {displacement|velocity|angularvelocity|temperature|porepressure} <ID>

To display a list of initial conditions, the command is applicable:

list initial {displacement|velocity|angularvelocity|temperature|porepressure} [all] <ID_list>

To delete the initial conditions in the dialog mode, in the radio button group Action (step 3, see above), select Delete. This action corresponds to the command:

delete initial {displacement|velocity|angularvelocity|temperature|porepressure} [all] <ID>
