Re: Result becames strange in an edited model

Hi Peter If I take the emissivity away."WARNING:: GetParentMatProp: Property Emissivity not in either parents!"occurred. Then I set the emissivity in BCs,the code in solver log becames like this: ELMER SOLVER (v 8.3) STARTED AT: 2019/05/15 16:19:16 ParCommInit: Initialize #PEs: 1 MAIN: MAI...

Re: Result becames strange in an edited model

The iron in first one doesn't have any radiation boundaries.
I directly use the matearials defined in original file and make them correspond to bodies correctly.(And air is divided to different heat conductivity)
Maybe there're something wrong with model?
Thank you.

Re: Didn't compute well

I‘m sorry that I’ve forgot the SIF file.
Thanks a lot.

Result becames strange in an edited model

Hi I'd like to do a simulation about thermal transfer in a wall.Once I changed the thickness of a kind of material,the computed result becames strange. Condition and material setting is the same as original model,but there's something different in solver log. Here're the code of the original one: EL...

Thanks a lot.

Maybe it's the elmerGUI‘s error,I'd like to install it again.

Re: Segmentation fault - invalid memory reference.

Hi

I changed it to steady state.
And here's the mesh file exported by salome.
Thank you.

Segmentation fault - invalid memory reference.

Hi I was running a simulation about heat transfer between air and wall. But error "Program received signal SIGSEGV: Segmentation fault - invalid memory reference."appeared when running. I have no idea about what's wrong with it. Here's the solver log and sif file. ELMER SOLVER (v 8.3) STAR...

Re: Boundary condition

Thank you,it does work now.Outdoor side has temperature change now.
But I'm not sure that if it's right because indoor side with 24°C of air is still the same.
Here's my setup.

Re: Boundary condition

Hi,

Thanks a lot!I tried to set it to idealized(by the way I may didn't turn on the convection before).But this time warning"WARNING:: HeatSolver: Convection model specified but no associated flow field present?" appears and result didn't change.
Here's my solver log file.
