The code CrysMAS supports the local 3D fluid dynamics calculation. The 3D computation takes place on the 3D block structured mesh.
The premise for the setting of the 3D model is the structured mesh in regions where the 3D convection should be considered. Therefore generate first the 2D structured mesh.
Then open the dialog 3D Grid .
Select regions where the 3D model should be initialized. The number of selected regions will occur on the top of the dialog window.
Enter the number of azimuthal planes N for the 3D model in the dialog field number of azimuthal planes. The 3D mesh will be generated by copying of the 2D structured mesh N times by its rotation about the cylindrical symmetry axis.
Note
If the 3D mesh was already generated in the selected regions, then a positive number of azimuthal planes will occur in the dialog field number of azimuthal planes. A change of its number will reallocate the 3D data which was computed and stored on the existed 3D mesh. Therefore make a backup in advance. Select all regions in the model which were meshed 3D and only then proceed with the changing of the 3D model size. The prescription of zero azimuthal planes will delete the 3D model completely.
Accordingly press OK button. The 3D data structures will be created and the model will be prepared for treatment of the 3D convection. The total number of nodes in the 3D model will be equal to the number of nodes of 2D mesh in the selected regions times ( number of azimuthal planes + 2).
