Simple Thermal Simulation question

Anonymous — Fri, 02 Mar 2018 22:09:48 GMT

I have a 400x400x12mm aluminum plate that I want to run a simple thermal simulation on. My desire is to see how long it would take for the plate to reach a specific temperature B starting from initial temperature A, with ambient air temperature C.

So for example: 100c to 25c takes 50 minutes with an ambient temperature of 25c.

I'm super new to this, so how would I go about setting up this simulation?

Hi @rhys.wiebe,

Thank you for your posting!

In Fusion simulation, we only support Steady Staus thermal analysis and it's accepted as a Future consideration in Fusion 360 ideal station.

Thermal: Determine the steady-state temperature distribution and the resultant heat flow. Available thermal loads include applied temperatures, surface heat sources, convection, radiation, and internal heat generation. The thermal conductivity of the material must be known as well as the ambient temperature and heat transfer coefficients at convection or radiation load surfaces.

Note: Because Fusion 360 thermal simulations are steady state, at least one temperature-based thermal load is required in the model to simulate heat transfer. The steady-state solution represents when the model has achieved thermal equilibrium. That is, there is a balance of heat input and heat output, and the temperature distribution remains constant.

If you want to know the time when it reaches out to the status temperature, it's not possible in Fusion 360.

However, regardless the time, If you want to know the status temperature, it's possible.

I created a sample without the time condition. Here is how to set the thermal analysis.

In this case, you need a convection transfer coefficient. If you don't know the exact values, you can use this.

If you have further questions, please let me know!

Many thanks,
