<div>Dear trnsys users,</div>
<div> </div>
<div>I am now trying to use type 556 in trnsys15 to simulate ground heat exchanger. But as I start the simulation by using this component I got the error "Error Reading Gauge1.progress: Invalid floating point operation." I have not change anything in model, just I am using the sole (only type556 and nothing else) type in the project and simulating. </div>
