How to handle errors that occur during proii simulation
Thread Content
2 error(s) were encountered during simulation, along with 0 warning(s) and 0 messages: *** Error *** Unit 1, ‘t1’ – for a packed column, it is necessary to specify the liquid viscosity and surface tension values in the thermodynamic method sets that are used. *** Error *** Unit 1, ‘t1’ – for sieve trays, a liquid viscosity method must be specified within the thermodynamic method set being utilized. How to resolve this?
In the thermodynamic approach, a method for calculating the viscosity of the liquid must be specified.
