Dear TRNSYS users,
I use TRNSYS 18 for solar absorption cooling system as in Fig.1. While i set the simulation time step was 5 minutes, the system can simulate. However, when i changed the simulation time step into 30 minutes or 1 hour, the system cannot operate. The TRNSYS program show 2 error that below(as see in Fig.2)
1.)TRNSYS Messsage 203 ---> A convergence problem was encountered. Modification of the TOLERANCES control card may cure the problem.
2.)TRNSYS Messsage 450 ---> The maximum number of warnings allowed per simulation has been exceed. Please fix these warnings or increase the limit on the number of warnings allowed per simulation
Then i wonder that why i cannot set the simulation time step at any time. Does anyone have any idea or solution?
Thank you for your comment.
