Development
The actual type of development is described by means of a number of parameters conducting a function or by a piecewise linear curve.
Piecewise linear curve
If you do not describe the whole period where the calculation takes place the program automatically chooses your value with the nearest abcissa.
When editing the table you can use the INSERT-, DELETE- and ENTER-keys. 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).
It is possible to load input-data from external data-files. The content of the file is copied into the b4cast-job, but for information only the origin is shown in the window. Using this feature makes the table uneditable.
Using the Clear-button erases the table and makes it editable.
A development can be Enabled or Disabled. A disabled development is not considered in the calculation. The stress analysis can not allow the E-modulus, the Poissons ratio and the thermal expansion to be disabled.
