Tools for Troubleshooting

   

During the creation of a model, situations often arise in which the calculation (simulation) displays one or more errors.

The toolbar "Error List" is used to localise the error.

In most cases, this is sufficient to eliminate an error. Sometimes, however, a detailed determination is required.

A frequently used strategy is

• cutting open streams and specifying individual variables (pressure, enthalpy, mass flow) with a signal transmitter (component 36), or also
• dividing the entire model into sub-models.

This task is supported by the following two commands:

A) A stream can be ‘sliced’ if it is selected and its context menu ‘Cut open Stream’ is selected via the right mouse button. The stream is cut into two parts at the position of the cursor. The stream values are copied to both parts.

B) For the

• start value setter (component 33) and for the
• the edge value (component 1)
• the measured value (component 46)
• the connector (component 132) and
• the limiter (component 147)

their context menu entry ‘Take over stream results to selected component’ is available for the general value input.

The pressure, enthalpy and mass flow of the stream are copied to the default values of the component.

For component 147, the default values INIM, INIP and INIH are used.

With these tools, it is possible to cut out parts of the model and determine them separately.
