Example G-5: 2D Part with a Randomly Distributed Second Phase

In this example, the graphical user interface (GUI) is used to create a 2D part in which in which a second phase is randomly distributed in the background. This example mirrors Example C-3.

The structure is 2D with a shape of 100×100 voxels and has a base material of 1 and a voxel size of 0.02 units in all directions. The parameter log_debug is set to True for demonstration purposes.

Afterwards, the parameters for the second phase are entered in the Model Manipulations tab. The necessary parameters are Second Phase Fraction which is set to 0.42 which means 42%, and Second Phase Material Code which is set to 2 resulting in the second phase having a material code of 2.

The part is then exported to an Abaqus™ input file in 3D mode with C3D8R elements. The Non-Empty elements (which happens to be the whole model), are requested to be exported.

The following figures show the various tabs of the GUI in this example:

../_images/ex_g5_random_2d_part_2.png — Fig. 48 The GUI’s “Model Manipulations” tab for Example G-4.

../_images/ex_g5_random_2d_part_3.png — Fig. 49 The GUI’s “Boundary Conditions” tab for Example G-4.

../_images/ex_g5_random_2d_part_4.png — Fig. 50 The GUI’s “Output” tab for Example G-4.

After filling the form, the model can be created by pressing the “Create Model” button. The screen automatically switches to the Run tab and will show the program log.

At the end of the process, a dialog box announces the completion and gives the path to the output file.

Also, the program log and a summary of model information will be shown in the Process Log section of the Run tab. It will also be written to a .log file in the output folder.

Finally, a configuration file based on the examples will be written to the output folder and can be used to import the model in the future. It will look like this.
