This is my lateset sif file, and it is working well as in the attached screenshot file. But here, I have one question, which might do something with the unit problem. Is "Heat Transfer Coefficient = 0.005" in Boundary Condition 1 appropriate? It is meant to be the boundary between concrete...

Thank you Kevin!

Heat Flux = Variable Time
Real
0 10000
600 10000
601 0
1200 0

This one worked very well.
You made my day, I appreciate you again for your big big kindness!

Thank you Peter! Adding "Coordinate Scaling = Real 1.0e-3" to the Simulation section worked perfectly with the original heat conductivity 1.7! All my problems including the heat transfer problem was resolved, and I now understand the conditions I set much clearlier than before. You made my...

Hi community! I want to make a model that for the first 600 seconds the surface is heated with heat flux 10000W/m^2, then after that for another 600 seconds it stops heating the surface and releases heat to the external air(external temperature = 288K). I would appreciate it if you would teach me ho...

You're totally right.
This was the next model, and the second object was supposed to be the defect inside the concrete.
Sorry to make you confuse.
Material2 and Boundary Condition 3 was supposed to be added to this sif in the next model.

Thanks for your kindness.

I successfully resolved this problem!
I don't know why but raising the heat conductivity to about e6 times larger made the heat transfer smooth.
However, I'm not sure about none of the values I've set, so I would be happy to be taught which part of my solver settings are still weird.

Hi community! This is my first post here. I'm having a problem in my transient heat flow. I made a 2D model that heats one surface of a concrete object. It is supposed to be heated from left to right, but what I got was different from that. The output obtained was a temperature distribution with alt...
