Solving options for transient problems

Solving options

You can find numerous useful options to adjust the solving process. Flux sets default parameters in an automatic way. The default values ensure the correct operation of the solving process under “standard” conditions of use. Under certain particular conditions, the user can modify these values. A list of the adjusting parameters dedicated to transient problems is presented in the paragraph below.

Initialization of the state variables at the beginning of a step

By default, the state variables are initialized with the previous step solution, except if there is any hysteretic material, the state variable will be initialized with a predicted solution. A solving option allows the user to modify the initialization to one of following options:

• With null solution,

• With a predicted solution,

• With the previous step solution (by default).
