I simed the expected temperature rise of a cube of water. A 1 kg cube of water applied 1 Grey is expected to rise in temperature everywhere by ≈ 0.25 mK Cube of Water - Volume: 0.1001 m * 0.1001 m * 0.1001 m = 0.001001 m³ Reason: I want mass = 1 kg. ρ ≈ 997 kg/m³ = m/V ∴ m = 997 * 0.001001 = 1 kg Ap...

Thanks!
It turns out Heat Source units are W/kg = (J/s)/kg

You got it

I had 3 volumes by accident. Easy fix then. Woohoo, that's good.

I would also like to know, about what settings/conditions I should choose to set up an ideal simulation. I want to apply 1 Joule of heat to a cube of water that weighs 1 kg. Thus I have applied 1 Grey = 1 J / kg. The expected temperature rise everywhere in the cube will be 0.25 mK, or 0.00025 K. Fir...

@raback I believe all of my units are SI.

Do you think this sort of result is accurate/realistic to the simulation/model?

Are you suggesting I change something in ParaView? I don't understand.

Thanks

Hello! I would like to apply 1 total Joule to my cube. How can I do this? I've discovered I don't understand "Heat Source". For example, when I apply Heat Source = 1, am I applying 1 Joule of energy/heat, continuously? If that is what I am doing, then how can I accurately apply 1 total Jou...

https://drive.google.com/file/d/1oFgnnC471xgmdKB_RAMtI0cmG4KPoi2y/view?usp=sharing I can check Gmsh, thanks! About combining bodies in Elmer, will combining those bodies have any consequences such as counting nodes or elements twice, double layered walls/boundaries, or anything like that? I wonder h...

Hello :D, It would be nice to know how I could make Fusion 360 (3D CAD) work with Gmsh/Salome and then ElmerGUI. I would build complex geometries on Fusion 360 -> export STEP -> Gmsh/Salome 3D mesh -> Open file in ElmerGUI. Unfortunately, I made a cube on Fusion 360 -> export STEP -> Gmsh 3D mesh ->...

I made an object in CAD. It has 6 bodies. https://imgur.com/a/ueocWvZ I discovered I could create volumetric meshes for FEA here. https://imgur.com/a/XNKFluH Could you recommend the best method to create a mesh for Elmer? Specifications: I'd like model/mesh IMPORT to Elmer to recognize that the obje...

Oh it's cooling. It's just barely cooling -> -.001 K change per second when the ext. temp. is set to 100 K and the object is heated to 274 K. Surprising.

Thanks kevin
