Model

A model should be identified by a user-defined name.

The actual type of boundary conditions is described by means of piecewise linear graphs.

Define in the table how the value is depending on time.

If you do not describe the whole period where the calculation takes place b4cast automatically extrapolates your values.

At any time, you can observe in the graph-window how your data is interpreted (your last key-stroke may not be interpreted until you move the cursor to another cell).

When editing the table you can use the INSERT-, DELETE- , TAB-, ENTER-keys and use copy and paste from the clipboard.

It is possible to load input-data from external data-files.

You can assign the same model to several surfaces just by selecting the surface by clicking the left mouse-button. Dragging the mouse over surfaces with Shift and left mouse button pressed, copies selection/deselection to the surfaces.

To position the structure in the right angle, you can turn it by means of the scrollbars, the arrow-keys or keep the left mouse-button pressed while you drag the mouse.

You can zoom in on a specific part of the structure by dragging the mouse with the left mouse button kept down, while the Ctrl-key is pressed. Zoom back out by clicking the right mouse button. Also, the mouse wheel can be used for zoom/un-zoom.

By means of the keyboard all surfaces on a specific volume or on the entire structure can be selected, see Overview Mouse and Keyboard actions

The selected surfaces will be marked with red colour.

Surfaces with the same model as the one you are going to apply are shown with an orange colour.

When the actual surface is participating in a casting joint, the model of the participating part will automatically be removed and the structure is considered monolithic.

If you apply a convective temperature model to a surface you also should apply a wind-speed model and vice versa.

If you apply a shield model to a surface, you also must apply models for convective temperature and wind-speed.

Instead of applying a wind speed model and eventually a shield model, a model for the convective coefficient can be applied directly. When using this model, it is also possible to define time points relatively to the time where the concrete is placed.
