How to change the units that appear in Aspen results
Thread Content
I’m a beginner with Aspen and would like to ask how to change the units that appear in Aspen’s results. For example, if the unit for flow rate is entered as kmol/hr, but it shows up as lbmol/hr in the result summary. Also, how can temperature units in Fahrenheit or pressure units in ATM be converted to degrees Celsius or MPa? Does it need to be set somewhere beforehand?
Switch to modify the local unit system in the top-left corner.
The unit is set in advance and cannot be modified in the exported results.
But even with local modifications, can’t the units of pressure and temperature still be converted to °C and MPa? The units I can convert here are only SI, ENG, and MET. Is that why I can’t convert it to what I need? Or?
How does one need to set it up in advance? Where is it usually set? Please give some advice. Thank you
Create a new unit system, such as US-1, according to your own requirements; then, still in the top-left corner, select the new unit system US-1 that you want to use.
It can be set in setup | specifications | units of measurement, and a custom set of units can also be defined
It can be set in Tools-Data maintenance-Units of Measure; there are Set1-Set3 available, which can be customized.
