Timestep Control
Max Relative Error
Enter a value in the field. The default is 0.05.
Max Absolute Error
Enter a value in the field. The default is 1.0E-5.
Timestep
Enter values in the fields.
This value is always in seconds.
- Initial: What is used as the initial time step. The default is
1.0E-7. - Smallest allowed: The smallest time step allowed during the simulation. This is required when using the automatic procedure to determine the time step. The default is
1.0E-7. - Max % of simulation time: The default is
10.
Factor Specifying the Maximum Increase in the Time Step Taken from One Time Step to Another
For example, if 2 is entered the maximum time step is twice as long as the previous time step taken. Enter a value in the field. The default is 2.
The Timestep is to be Controlled by the Phase Interface Displacement During the Simulation
The default is Automatic. When a liquid phase is entered in a simulation this option is automatically turned on. Optionally choose Yes or No to set whether the time step is to be controlled by the phase interface displacement during the simulation.
