Hi, The variable-dependent equation for reaction rate that you provide is similar to modeling Eq. 1.12 of heat equation in Elmer Models Manual (http://www.nic.funet.fi/pub/sci/physics/elmer/doc/ElmerModelsManual.pdf). The relevant code for the Heat Equation is provided at https://github.com/ElmerCSC...

Dear Anjali,
Keep it up with the work.

Yours Sincerely,

Dear Kevin,
Thank you very much for developing test cases for Kepsilon solver of Elmer software.


Yours Sincerely,

Looks like it works with a smaller timestep. In context of ElmerSolver,in order to attain convergence in the numerical solution, especially when coupling navier-stokes equations with heat equation, the timestep size can be designed an order smaller than the length scale size . E.g. if the length of...

Hi,
Can you show the simulation result of volume current density (Fig. 3 ) as shown in the following conference paper?
https://ieeexplore.ieee.org/document/8480595

Is the distribution of volume current density in the cylindrical volume uniform?

Yours Sincerely,
Anil Kunwar

Dear Anjali, The analytical equation [Eq. 3 in https://asmedigitalcollection.asme.org/heattransfer/article-abstract/140/7/072001/384794/A-Generalized-Analytical-Model-for-Joule-Heating?redirectedFrom=fulltext) for the joule heating in a regular cylinder of base area (A) and height (l) is given by: P...

What is the relation between length of the wire, radius of the wire and joule heating? I looked for the equation in Elmer Modes Manual (chapter 16) but couldn't find one. Thank you for any information you can provide. Dear Ilaj, If you look closely at Eq. 16.9 of the Elmer model manual, the unit of...
