Hi,
I was able to solve the issue with the help of some pointers from simulation experts (Mr. Jim Dirkes specifically). It was a complex mechanical arrangement where a couple of "Heat Exchangers" were modeled to have multiple loops to supply heating/cooling at different temperatures. Since everything was autosize somehow these capacity issues arose as highlighted in my original post. Simplifying the mechanical arrangement in a step-by-step manner leads to fixing the issue. I have never encountered such issues in a "Autosize" model but this time it happened AND I don't know the exact cause of this. However it got resolved by bringing a basic ingredient, "simplicity" in the model.
Hope this will be helpful to others.
Thanks,
