Hit Gas simulation: convection, radiation, conduction

[fraggle]

Hello,
I'm looking to build a small animation (like 10 secondes) to describe the air circulation inside an oven. It doesn't have to be scientifically true, but must look like scientific with color variation link to the thermal value, like this animation: https://www.youtube.com/watch?v=_YnvB1LTnXw

Or maybe I should look for a 2d flash animation?

Thanks

Once you have simulated (you need only the temperature channel), go to the Rendering panel -> Colors and Transparency -> Smoke Color. Choose Based On Temperature and use the color gradient to map colors to you temperature values (if you simulate with the default settings, the temperature will be between 300 and 2000 Kelvin). You will see the temperature interval marked with a blue area in the gradient itself. Then, go to the Smoke Opacity rollout, again select Based On Temperature and use the diagram to map the opacity to your temperature. You might use a constant opacity of 1 throughout, or lower than one if your sim is 3D, or anything more interesting

thanks for the tips,

I played a bit with it, but I face several major problem from the start and tutorial are not enough to know where to start from.
- gas burner : How to achieve a natural looking gas burner fire as per attached file? I try with a second Source but it doesn't work. Should I used pflow like in your flamethrower tutorial instead?
- Gas convection: the path of the gas should follow a dispersion according to pressure + temperature flow inside the cavity and should go around the plate right above the hob (emiter) before escaping the cavity by the holes on the rear. On my sim, it doesn't care about the plate, the smoke just go trough it like it doesn't exist!
I can't attached an image on this forum, so here is the link.

here is the image of the gas hob I willing to achieve:

To get smoother flames, try to increase the Steps per Frame option to about 10.
About the plate - make sure in its right-click Phoenix Properties that it's marked as a Solid object and that its normals are not inverted. If it still gives you troubles, it will be best to email it to support@chaosgroup.com so we can investigate.

Thanks,

as no good result have been achieve so far, I'm wondering if we can used any data imported from Fluent (Ansys soft) or any animation as a mapping to map (drive) the smoke color and flow to this animation?
The export format available from Fluent Ansys are: ABAQUS / ASCII / AVS / CGNS / Data explorer / EnSight Case Gold / FAST / FAST Solution / Fieldview Unstructured / I-deas Universal / NASTRAN / Patran / RadTherm / Tecplot. The solution can also be save as .msh
Thanks

Negative, Phoenix can import only Field3D and OpenVDB caches.

Anyway, the scene is absolutely do-able, if you send it, we'll find what's wrong and help you correct it.
