Initial Conditions | ||
In the Initial Conditions module the initial temperature, u-velocity, v-velocity and pressure fields are given. (Figure 1). |
|||
 Fig. 1 - Setup das condições iniciais. |
|||
| In the initial condition window u and v can be setted as constant values when a heat conduction problem is been solved in a moving solid. You have to set these velocities as also boundary conditions. In pure fluid flow problems the temperature is disabled (Figure 2), because it uses only the momentum equations, mass conservation and pressure. And in the fluid flow with heat transfer all the options are available (Figure 3). | |||

|||
In this module the last results of a simulation can be loaded as initial conditions, selecting LOAD FROM LAST RESULT (Figure 4). This option can be used when an interrupted simulation is re-started. | |||
 Figure 4 – Initial Conditions Setup |
|||
| The initial conditions can also be loaded of a data file (Figure 5), clicking in BROWSE and selected the parameter type to be loaded (Figure 6). The file to be read is ASCII type (file " * .dat "), being a data table i x j. | |||

|||
| If you need to load some of the Initial Conditions from a file, this should be the last step, since it will overwrite the previous values. Always remember to give APPLY to load the values to the problem (Figure 7), except when the values are loaded from a file. | |||

|||
| In the Figure 7 the conditions default and the user's conditions are shown. Those conditions can be visualized in a matrix form (Figure 8), and in the window of the post-process 3D (Figure 9) clicking with the right button of the mouse on the desired field (Figure 10). Click then in DATA for visualization of the matrix or in DATA VIEW for 3D visualization. |

| The SAVE AS option saves the data in a file, which can be loaded later in another problem, as in the Figure 5. |
