Coupling thermal and electrostatic solver

Hello, I am (again) working on coupling HeatSolve and StatCurrentSolve for a steady state, iterative solution. It looks like this can be accomplished by setting the current source term in StatCurrentSolve (drho/dt) and by setting the heat source term in HeatSolve (h) after each iteration. The proble...

Re: Error in Axisymmetric Thermal Model

Yes, the heat flow (Watts) was calculated using a sum of the Temperature Loads on the boundaries.

Error in Axisymmetric Thermal Model

There appears to be an error in the Solver. I'm using solver library version 5.5.0. In a simple axisymmetric model of a hollow cylinder with the inner and outer temperature fixed, the heat flux is low by 6.28X (ie 2*pi). Thermal resistance of a cylinder radially is ln(outer radius / inner radius)/(2...

coupling thermal and electrostatic solvers indirectly

Hello, I would like any advice anyone would have about how to build an analysis that has the thermal and electrostatic solvers indirectly coupled. This is one way to include thermoelectric effects when they are not included in any solver. For example: 1. The solver would iterate the thermal solution...

Re: Saving Heat Flow using Savescalars on internal boundary

Hello, Thank you for your help. I ran several runs to look at your recommendations. I attached a screen shot of the results. Run number 8 is a baseline run. a. the use of 'Flux Integrate Body = X' Run 9,10, and 11, as compared to run 8 show the effect of using 'Flux Integrate' in the boundary specif...

Saving Heat Flow using Savescalars on internal boundary

Hello, Thank you all for the assistance in the past. I am trying to extract the heat flow (W) from boundaries between domains that are internal to the model. Is there an accurate way to output the heat flow from internal boundaries? The topic of getting heat flow from boundaries has been discussed b...

Re: Saving Heat Conductivity to VTK XML format

Thank you, after some trial and error, the following does allow 'Heat Conductivity' to be solved and stored as a field scalar, then exported to a VTK file (along with temperature). Thanks so much. Solver 3 Procedure = File "SaveData" "SaveMaterials" Parameter 1 = String "Hea...

Saving Heat Conductivity to VTK XML format

I have a thermal simulation with variable heat conductivity. I would like to export the values of heat conductivity, along with Temperature to a VTK XML file. Exporting Temperature as Scalar Field 1 works, but Heat Conductivity does not work as Scalar Field 2. Is there a way to export Heat Conductiv...

Re: editor for working with .sif files

Thank you. If I get syntax highlighting working well in bluefish or emacs, I will post it.
Thanks

editor for working with .sif files

Hello, I am new to elmer, and am finding it efficient to work directly by editing the .sif files (rather than working in elmergui). Is there an editor that works well with elmer, that would allow for syntax highlighting, etc., such as is done in many editors for c or xlm code, for example? I am usin...
