This menu is used to control the color, thickness and number of pathlines displayed when using the Display Particle Tracks Group function. This function is toggled on or off using the Pathlines Tab. It also controls the Filling Speedup parameter. Options available are:

These options will be explained in the rest of this unit.

Show mold parts

In most cases you only look at the metal portion of the model, that is, the casting, gating and risering. There may be times, however, where you would also like to look at items in the mold, such as chills, sleeves, etc. Show mold parts allows you to toggle the display of these extra pieces on and off. The two figures below show a model with mold parts off and with mold parts on.


Symmetry planes

A common method of speeding up simulations is to use one or more planes of symmetry, when the model has mirror images. For example, the model below has two planes of symmetry which are represented by the grayed-out areas:

In this particular case, using planes of symmetry can reduce the model size to one-quarter, without sacrificing simulation quality at all. This also means that results come four times faster!

When a SOLIDCast model is meshed using planes of symmetry, FLOWCast has the ability to display the filling process on the entire model, by mirroring those results on the display. The Symmetry planes function is a toggle switch, which controls whether the display data is mirrored or not. The default state is Auto. That is, the data is automatically displayed on the full model, so that the complete model fills. If Symmetry planes are turned off, then the data will be displayed only on the meshed portion of the model, which may be only one half or one quarter of the full model.


The two figures below show the effect of using the Auto and Off settings for the Symmetry planes function:

There are three functions that control the display quality of metal flow pathlines. They are described here.

Pathlines color

Select Settings… Pathlines color, to choose the color of the flow lines from the following palette:

Pathlines thickness

If you select Settings Pathlines thickness you have the opportunity to change how heavy the pathlines are drawn on the model, as shown here:


Pathlines number

If you select Settings Pathlines number you can choose the relative number of pathlines that are displayed, from Min, Med, Large and Max. This option is displayed below and is also available on the Pathlines Tab:


As with the pathlines function, there are three controls for display of velocity vectors.

Veloc vect color

Select Settings Veloc vect color, to choose the color of the flow lines from the following palette:


Veloc vect thickness

If you select Settings Veloc vect thickness you have the opportunity to change how heavy the velocity vector tails are drawn on the model, as shown here:


Veloc vect head size

This function controls how large the white head of the velocity vector is.

 Filling speedup

If you select Settings… Filling speedup, you have the option of adjusting how fast the FLOWCast Full Simulation runs. Options are a speedup of 0, 1, 2, 3, 4, 5 or 6.

The speedup number refers to the number of pressure field computations to skip for every liquid/gas interface advance and temperature change due to convection/conduction computations. 0 represents no skipping of calculations, and no additional speedup.

By skipping some of the pressure computations, the simulation will go faster, but at the sacrifice of some simulation accuracy. As the speedup increases, you will tend to notice a rougher liquid/gas interface, with more splashing particles, or flotsam .

Higher speedup values should be used on initial simulations, or with very large models, where computation time becomes a significant factor. Final simulations should be done with a speedup of 0 to insure the highest accuracy. This is the default condition.
