Defining batch parameters

Step 1: Set control parameters

Procedure

1. Go to Parameter or Simulation mode.

2. Select Study parameters in the Configure menu.

The Study Manager opens. It contains two tabs: Parameters and Studies.

3. Select the damper submodel.

The Parameters view shows its parameters. If this is not the case, select the Show/Hide > Parameters menu item in the Edit menu:

4. Drag and drop the damper rating:

into the Input parameters list of the Parameters tab, or,

directly into the parameters list from the Studies tab.

5. Go to the Studies tab.

6. If it's not already the case, select the damper rating in the parameters list.

Step 2: Set values for control parameters

There are two methods of setting the values for each control parameter:

• Varying between 2 limits

• User defined data sets

Results

If you want a text parameter to be a batch control parameter, you must use the option User defined data sets.

In our example, however, we will use the setup method drop-down list to enable the option Varying between 2 limits to define the values of the damper rating.

Batch setup method: Varying between 2 limits

batch set up method varying between 2 limits

This method can be used if the batch parameters are real or integer. With this method for each control parameter you must specify:

• a base value,

• a step size,

• the number of runs to be performed below the base value,

• the number of runs to be performed above the base value.

Note

If you have N control parameters and you specify M1,M2,…,MN different values for the control parameters, there will be M1xM2x…xMN runs.

By default the value field is the same as the value currently set and displayed in the component.

To get the sequence of parameter values we want:

Procedure

1. Set the Step size to 200, specify Num below to be 3 and Num above to be 3.

2. Click OK.

You could equally well have used the setup method with User defined data sets enabled.

Batch setup method: User defined data sets

batch setup method user defined data sets

This method can be used if the batch parameters are real, integer or text. You must specify how many data sets you require. Do this by clicking on Add and Remove as required. For each control parameter you must specify the value.

If you have N data sets, there will be N runs.

In the current example, if you use this method, you would create 7 data sets with the values shown in the following figure.
