Re: Noconforming mesh

Hi Peter, Thank you a lot for your answer. Do you think i can use mortar to solve heat equation with 10^4/6 mesh elements (and maybe around 10^3/5 mortar elements) ? I'm not exigent about the temperature relative error, only 10^-2. I have a 2D (but also 3D after) global domain composed of many nonco...

Noconforming mesh

Hi everybody,

I'd like to know if Elmer can work with nonmatching meshes ? Is there some DDM inside like Mortar method ? I'd like to handle a complex geometry divided into components without meshing the all geometry.

Best regards.

Re: Transmissivity

Hi,

That's what I thought. My goal is to simulate the heat in a double/triple glazing window with a transmissivity for each glass. No way for that with elmer ?

Transmissivity

Hi,

Can somebody explain me where Transmissivity coefficient is used on the heat equation / radiation model ?

Thanks for your help.

Hello,

It'll be nice to have the same dev for Elmer, i mean using python natural language for sif file.

Re: Radiation, test case

Hello Peter, Thanks a lot for your answer, in fact the issue was the too large conductivity value. I do understand the way to compute the flux via the load temperature but i don't understand why i do not get the same value using the diffusive flux and the convective flux as show below Operator 1 = "...

Radiation, test case

Hi, I'm trying to find some results of a basic radiation test case. It's a vacuum cavity between two concentric cylinders as shown below. radiation.PNG r1 = 0.07m r2 = 0.08m r3=0.14m r4=0.15m. - The cylinders are perfect conductors i.e. conductivity = 100000000 - At the inner surface of the smaller ...
