surface average temperature

I want to model a concrete slab with a void inside the concrete. It is a thermal analyse where I apply a heat flux to the bottom surface. Within the void heat is transferred by radiation and convection. For simulating heat convection within the void, I use the surface film condition function in interaction module. I have to define the film coefficient and sink temperature. I decided to use the average temperature of the void surface for sink temperature. I don’t know how to define the average surface temperature. I think I have to use Abaqus Subroutine.

Greetings,

I'm working on thermal analysis of concrete filled steel tube columns.

I used all the guidance I could get  from the research papers, but I still didn't get the results I want.

In fact, all the job analysis I run ended up abrupted. 

I attached my abaqus work for your kind attention and perusal. 

Any suggestions and tips that might help me overcome my problem is more than welcome. Perhaps I could get some pointers whict part in my analysis is missing.

Thank you.

Applying heat flux for a specific amount of time using ANSYS

Hi everyone,

how can I apply a 'X' amount of heat flus for a specific amount of time? It'll be helpful to include the steps especially for the part on specifying the amount of injection time (say 3 micro seconds)

 

Thanks!!

Modeling heat transfer involving a phase change (ice to water) using Abaqus

phase change

I'm modeling the transient heat transfer of a cooler with an ice pack in it. How does one accurately model the phase change of the water? Here's what I've tried so far:

 1. Added latent heat property to material card. Used Latent heat = 334 kJ/kg, Solidus Temp = 0, Liquidus Temp = 0

   Result: Error, Solidus and Liquidus temps cannot be equal

 2. Solidus temp = -0.01, Liquidus temp = 0.01

   Result: Analysis ran, but diverged very early in the analysis.

material deposition to substrate simulation at ABAQUS

Hi;

I am trying to simulate material deposition to substrate. In our case material is added to substrate  and there is a distributed heat flux with constant velocity acting by node by node. I want to simulate showing the added material in the simulation and its effects. There is a command for that called Model Change in the ABAQUS. So is someone familiar to that kind of problem. And also I need to account mass diffusivity while the material is melting.

I will be gratefull for any advice you can spare

Best Thanks
