Using a condition sequence to define a solution

1. Create a new Simulation

When defining solutions based on a condition sequence, it is generally a good practice to begin with a new, empty Simulation file. Right-click an existing FEM or assembly FEM file and choose New Simulation to create the Simulation file. If you are automatically prompted to create a new solution, in the Solution dialog box, click Cancel to ensure that you create a new Simulation with no solution.

2. Import or create a condition sequence

You can import an existing condition sequence from a file, or create a condition sequence from the Condition Sequence Manager dialog box.

To import a condition sequence, see Import a condition sequence.

To create a condition sequence, for best results, define the condition parameters, conditions, and condition sequence in this order:

1. Create condition parameters.

2. Create conditions.

3. Create a condition sequence.

3. Define boundary conditions

Use the expressions that the software creates for the condition parameters to define the magnitude of boundary conditions.

For more information, see Define a boundary condition magnitude with condition parameters.

4. Create a solution

Use the New Solution from Condition Sequence command to create a solution from the condition sequence.

For more information, see Create a solution from a condition sequence.

Alternatively, you can create a solution using the New Solution command. In that case, however, you must manually define the evaluation times, time steps, time step intervals, and so on.

5. Assign boundary conditions to time steps

When you create the new solution from a condition sequence, there are no boundary conditions included in the solution. Depending on the solution type and size of your model, you can assign boundary conditions and time steps in several ways:

• In the Simulation Navigator, you can drag and drop boundary conditions directly into the appropriate container in the solution or time steps.

• In the Simulation Navigator, you can right-click a boundary condition and choose Add to active solution or step.

• Depending on the solver and solution type, you can use the Step / Subcase Association Manager dialog box to distribute loads and constraints among multiple time steps.
