Welcome to the TRNSYS Users Forum.
The forum is a place where people can interact and have discussions about different topics involving the use of the TRNSYS software package. Here you can post topics for discussion or questions on using TRNSYS and get advice from other users or TRNSYS experts. This forum is not intended for detailed technical support. Users should contact their distributor’s hotline for such assistance.
Some tips for success on using the forum:
- Follow the Forum Rules posted in Forum Administration.
- There are categories for different types of topics and questions. Post your topic or question into the proper category.
- Before posting a topic or question search the existing topics (and the TRNSYS Users listserv archive or Post archive) to see if a similar topic or question has already been answered.
- Use a descriptive topic name. Don’t use attention getting subjects, they don’t get attention and only annoy people.
- State the version of TRNSYS and which add-ons your are using.
- Include enough specific details for your topic of question to be answered. Just posting “Why am I getting an error?” without describing the specific error and what you are trying to do when you get the error will not receive a response that fixes your issue.
- Remember when people help you, they are doing you a favor. Be patient, help people out by posting good descriptions of what you need help with, and be polite even if a response does not solve your issue.
- Moderators may edit your post for clarity or move your topic to a more appropriate category.
Now, i'm working on adding coolprop to my system, when i call enthalpy values of air at 78.91 K and P 1.02 bar it gives me floating point error, while on the online coolprop it results with a value normally?
Air
At the specified state point
| Temperature [K] | 78.91 |
| Pressure [Pa] | 102000.0000000211 |
| Vapor quality [kg/kg] | -1.0 |
| Speed of sound [m/s] | 865.443306349795 |
| Density [kg/m3] | 875.1744843827079 |
| Enthalpy [J/kg] | 14.052974687553103 |
| Entropy [J/kg/K] | 0.1689050106691501 |
| Constant-pressure specific heat [J/kg/K] | 1932.908870956434 |
| Constant-volume specific heat [J/kg/K] | 1050.4550445961488 |
if the temperature is 82 K the enthalpy at coolprop at trnsys and online coolprop is the same 205 kj/kg but when it comes to 78.91 or mainly below 82 and 1.02 bar the enthalpy is infinity! while it's not infinity on online coolprop
There was a bug in the CoolProp interface where the pressure was passed with the incorrect units. This was corrected in version 18.06.0000. You should contact your TRNSYS distributor concerning updating your TRNSYS version.
