4.2.2.1 Quantity Initialization

Next: 4.2.2.2 Scaling of Quantities Up: 4.2.2 Grid-, Model- and Previous: 4.2.2 Grid-, Model- and

Several methods are possible to initialize a quantity:

initialization of the quantity throughout the whole mesh with a constant value:
```
Value(<QuantityName>) = <const>
```
initialization of the quantity with a distributed analytical user definable function:
```
Value(<QuantityName>) = Analytical <function>
```
the quantity will be initialized with a distributed attribute defined on the given source file (no interpolation is necessary)
```
Value(<QuantityName>) = Read <attribute defined in the source>
```
the quantity will be initialized with a distributed attribute defined on any other grid and needs to be interpolated depending on the scaling factor of the quantity
```
Value(<QuantityName>) = Read(<physical>,<logical>) <attribute>
```
