DYNAMIC BOUNDARY
Curve parameter type
With the dynamic version of the software you'll have another kind of parameter for temperature, flows and humidity: a curve.
For example, a curve represents the temperature on a boundary condition during a period of time: X axis is time and Y axis is temperature. Please see curve editor documentation for more information.
Heat flow
An additional heat flow rate on a boundary condition can be specified on "Air temperature" kind of boundary.
Moreover, there's a new type of boundary: "Flow". This lets you specify just a flow rate on a specified boundary.
Dynamic time
Additional parameters are needed in order to perform a dynamic simulation. They can be found under "Dynamic time" in boundary tab.
The unit of time used by these parameters is determined by the choice on the same group: by second, by minute, by month, etc:
active: dynamic simulations will be performed only if dynamic time is active;
start time: time when dynamic simulation has to begin;
end time: time when dynamic simulation ends;
static simulation offset: every dynamic simulation will start from a "static" simulation (i.e. a standard simulation). If offset is zero, static simulation will be performed at start time; if offset is more than zero, static simulation will be performed at time start time – offset, then a dynamic simulation will be performed up to start time and it won't be visible by the user.
Let's consider the following example: suppose you have to analyse the dynamic behaviour of a wall during a specific day of a month and you have set the boundary conditions for the whole month. A good approach is to set start time to the beginning of the day, end time to the end of the day and static simulation offset to one or two days. In this way dynamic simulation will take into account also previous days.
