Response (status = PROCESSED)
The output of this calculation is the stream output which is common result output for all OLI's flash calculations or an error. In addition to this output the result also contains the solution temperature/pressure which can be conveniently retrieved from the data.result.calculatedVariables array
data.result.calculatedVariables [ { } ] | type | description |
name | string | name of the calculated variable, i.e. temperature or pressure as specified in input params.calculatedVariable |
value | number | value of the calculated variable |
unit | string | unit of the calculated variable, which is the same as specified in the input initial guess, i.e. params.temperature.unit/params.pressure.unit in input |
