[TRNSYS-users] Convergence failure in the simulation

[h8304506 at hkusua.hku.hk]

Dear all.

I am simulating a GSHP system, but receive warnings that some units do  
not converge at particular time steps.  The simulation stops after the  
number of warnings reach a limit.  I try to adjust the minimum  
relaxation factor and tolerance of convergence in the control card,  
but it seems to have no improvement.  Please advise how I can fix it?   
Thank you!

Yours sincerely,
