Can you attach the model?
@Ankit Naik You can go through this model which I created for transfer of Water.
I am not sure what is triggering the error.
I guess it might be due to the absence of a source component and improper initial values. I have attached a working model here: https://amoeba.wolfram.com/index.php/s/FraFRbYNy2NAXYQ
