Hi,

I have been working on a thermal simulation, and I need to define constant heat (W or W/m^3) inside a solid. I'm using fvOptions, I have followed the examples from others posts..... And, when I have defined a solid, fvOptions hasn't worked but when I have defined a fluid, it has worked correctly. Why?.... I don't know. May be, the problem would be a error code.... I'm using openfoam 2.3.0.

{
type scalarSemiImplicitSource;
active on;
selectMode all;

scalarSemiImplicitSourceCoeffs
{
volumeMode specific;
injectionRateSuSp
{
h (5e+09 0);
}
}
}


could anyone help me?

greetings

Hi all,

I confirm, it does not work in solid. I tried to do this by adding source directly to the equation for solid in chtMultiRegionSimpleFoam, but then temperature rises to infinity.

hi loook,

I've achieved that heat source in solid works, but no how I want....
It works when I use chtMultiRegionFoam (no steadyState) and it doesn't work with chtMultiRegionSimpleFoam (steadyState).... I don't understand it and don't know why.

My heat source of fvOptions is a semiImplicitSource.

does anyone know the answer?

Thanks.

Hi Cartuns11

I have managed to make it work using openFoam 2.4. I am using chtMultiRegionSimpleFoam with following fvoptions

heatSource
{
type scalarSemiImplicitSource;
active on;
timeStart 0.;
duration 1e6;
selectionMode all;

scalarSemiImplicitSourceCoeffs
{
// volumeMode absolute; // Values are given as <quantity>
volumeMode specific; // Values are given as <quantity>/m3

injectionRateSuSp // Semi-implicit source term S(x) = S_u + S_p x
{
h (6.2e8 0);
}
}
}

Everything is working fine...

Thanks!
I'll do it!

I've done it, and now, the heatsource (fvOptions) works inside solids.

Thanks!
