Detected nonfinite (Inf or NaN) values while evaluating equations or their partial derivatives at the 
start of initialization. Such equations may cause the initialization solve to fail. In order to fix 
this problem, you can either modify some equations or set different prestart values for some of the 
variables involved. The equations are listed below, as well as their prestart values in computational units.

Please tell reason for this error. I cant understand this. Came while siumlating this in simuscape thermal liquid. Please provide possible solution.

Thanks in advance.

The reason of this error popping up is probably (1) the way the model is built, and/or (2) parametrization of components, and/or (3) initial conditions. Some more details on the model, snapshots or the model itself, would help better identify the problem.
