Multicalc is a feature which allows for multiple calculations to be made at once. This can be useful for optimizing operating parameters, part load calculations, comparing multiple product configurations and much more!
Multicalc is open for all non-Demo users of SWEP SSPTM. It is accessed through the navigation panel in SWEP SSPTM under calculation or by pressing open in multicalc in any calculation window. Multicalc will then open with the inputs from the calculation.


First, you need to select what type of calculations you want to add to your Multicalc calculation. This is done in the Select a calculation drop-down menu. All calculations except for Air Dryer, District Energy and Two stage are available.
After selecting which calculation you want to use, the input window will appear. Inputs in this window work the same way as in a regular calculation window. When done, add the calculation to your Multicalc by pressing the Add calculations button


Moving parameters is a unique feature in SWEP SSPTM. With this feature SWEP SSPTM can automatically create sets of calculations with step-wise changes of the input parameters.

Select what parameter you want to move and then define the range. Either by entering the desired step size, number of iterations or the parameter boundries. Two examples can bee seen in the screenshot below. There is a limit of 50 calculations.

Multicalc calculations made in SSP G8 can be imported into SWEP SSPTM with the Import feature.

Pressing Calculate will run the calculations. When finished it it possible to view the results of each calculation. Pressing Export will create a downloadable Excel which can be used for further analysis.

Within Multicalc it is possible to visualize the results with charts. In this example below a set was created using the Moving parameters function. The set consists of a Water-Water calculation with B28 with a plate count of 20-40 plates.

After running the calculation clicking Chart will open the chart window.

Using the drop-down menus, select the parameters to use in the chart. In the example below, number of plates was plotted on the x-axis and pressure drop on side 1 was plotted on the y-axis, visualizing how an increase in number of plates will result in a lower pressure drop.

It is possible to save and share multicalc calculations with other users of SWEP SSPTM. This is done by clickin Save calculation. A window will appear were it is possible to name, comment and add tags.


Saved calculations are accessed via the navigation.
