Problem Statement: This knowledge base article describes the behavior of Aspen InfoPlus.21 when the historian file, tune.dat, has become corrupted, but is still in a usable state, or if the parameters in the tune.dat have been set to zero. | Solution: 1) The following Aspen SQLplus statement returns no rows.
Select occnum, fs_start_time from DiskHistoryDef where name=TSK_DHIS;
2) In the Aspen InfoPlus.21 Administrator the column % Full shows 0.00 for each existing fileset.
3) In the Aspen InfoPlus.21 Administrator the History Parameters shows 0 and 0... |
Problem Statement: Thermodynamic states the relation between enthalpy (h), Gibbs energy (g) and entropy (s): g = h - T * s (where T is the absolute temperature).
When checking the stream results in conventional solid substream, one can observe the relation is not satisfied. Why? | Solution: When reporting the default stream property solid SMX for a stream, whether in the MIXED or CISOLID substream, we calculate the property as a mole-average of the solid species, because Aspen Plus handles solids as pure phases, not as solidSolutions. The value is correct.
When reporting the prop-set property s... |
Problem Statement: What does equipment material cost include? What does it not include? | Solution: Equipment material cost includes the following:
Cost of the parts of the equipment, such as internals, shell, nozzles, manholes, covers, etc.

Shop and office overhead
Vendor engineering, shop drawings, shop testing, certification, typical manuals, small tools, and accesso... |
Problem Statement: Why is there no effect on my piping costs when I add a Rupture Disk to my Above grade or buried pipe component? | Solution: A Rupture Disk (RD) is considered an instrumentation cost (COA 683), so its cost is associated with instrumentation.
Keywords: piping, rupture disk, RD, instrumentation, COA 683

Problem Statement: What are the Design gauge pressure Inlet and Outlet fields for the compressor setup? What information are these fields requesting? | Solution: These fields are requesting the design (not operating) gauge pressure of the gas entering the compressor (low pressure) and exiting the compressor (high pressure). Typically, the design inlet and outlet pressures includes a safety factor over the operating pressures.
For instance, for the compressor modeled... |
Problem Statement: How can I estimate Orifice Plates? | Solution: One way to estimate an orifice plate is to add an Above grade or buried pipe component and include the fitting OP | Orifice plate and union and its quantity. Set the pipe diameter as needed and note the minimum pipe length is 1 ft.
Alternatively, you may use the Equipment or Unit Cost Libraries to store th... |
Problem Statement: How do you send all welds to shop for all equipment at once? | Solution: Construction management cost is part of Indirect. By default, Engineering management and Construction management fields are blank. To drive generation of estimated of engineering and construction management costs, a contractor MUST be specified. If there is no line item in the output report for Code of Accoun... |
Problem Statement: Can you link cost variables from Aspen Process Economic Analyzer (APEA) to Aspen PLUS Dynamics or Aspen HYSYS Dynamics? | Solution: No, you cannot link cost variables from APEA to Aspen PLUS Dynamics or Aspen HYSYS Dynamics. Cost analysis using APEA is supported for steady state mode only.
Keywords: Cost Variables, Cost Variables Linking

Problem Statement: On the General Wage Rate/Productivity-IP Box under Project Basis View, I entered manually all the Craft Wage Rates for all the craft code. Now I need to reduce the wages by a percentage (%). Instead of revising all the wages, is it a possibility to just reduce the wages by a percentage basis? | Solution: Yes, it is possible to reduce the wage rates in one field. This however requires creating a new construction workforce (CWF).
Let's say, CWF #1 was created previously, where the craft wage rates are defined.
Now, create a second CWF and adjust the craft wage rates as a percentage of CWF #1 as follows:

Problem Statement: Why does changes to the Total Construction Weeks change the Total Project Costs? | Solution: The construction schedule is integrated with the cost estimate to provide the basis for estimation of schedule-dependent costs such as equipment rental requirements, field supervision and construction management. Because of this dependence, changing construction weeks will impact the project total costs.

Problem Statement: How do I create a Code of Account (COA) exception and when should it be used? | Solution: Consider a scenario where you want to allocate fittings on a pipe, such as valves and bolt-up connections, to a different COA other than pipe erection. This can be accomplished by creating exceptions in the Code of Account. In this example, to allocate these to a different COA, you will have to create excepti... |

Problem Statement: Is there something to consider for leaving the equipment as it is? This is not demolition, this is a component already present in the project but does impact the cost because of the connections and so on that will be different. | Solution: For an existing equipment, select “EXIS” as the installation option field of the component.
For additional cost associated with this component, you can then use the “Mat’l/ man-hours additions” form from the “Options” drop down menu.
Other installation options are explained on article 97099.

Problem Statement: How do you send all welds to shop for all equipment at once? | Solution: There is no direct way to send all welds to shop. You can select “RMT” in the project basis view but if the length exceeds the limit, some of the weld will be done in the field.
However, for each piping component, you can put 100% in the “Percent of welds in Shop” under Options > Pipe -Item Details.

Problem Statement: When I change Percent calculated hours for Home office construction services, under Engineering Workforce | By Phase, it seems to have no effect. | Solution: Home office (HO) construction services are calculated based on the engineering workforce (EWF) performing the task. To capture any customization of costs for home office construction services, the EWF needs to be linked for the contractors doing the installation (see below).
Otherwise, the system is going to... |
