Hello

I am new to solidworks so sorry for my ignorance

I want to calculate how long it takes to a liquid inside a tank to cool down to room temperature

the hot liquid is in the inner tank and its being cooled by water in the outer tank in the image.

I looked for tutorials but i couldn´t find any that does this problem.

In the flowsimulation i establish boundaries, liquid temperature and materials but i can´t establish goals that solve my problem.

If anyone could help or show me a tutorial i would apriciate.

sorry for the english
