Hello Rich, The test files you mention might be a good resource help since I am trying to simulate the diffusion case that you addressed. I have been searching elmerfem/fem/tests folder in the usr directory, however there is not any under that name, adv_diff1 or adv_diff2. I also searched in the Elm...

Hello Rich, The sif file I have attached is based on the last sif file that you modified. The goal I am trying to achieve is to obtain just the diffusion transport in body 2. In order to do so, I added a second material, material 2, for body 1 and 3, with a very low Concentration Diffusivity and hig...

Hello Rich, Thank you for your answer. After deleting the ResultOuputSolver and just leaving the command "Post File = case.vtu" en the simulation section I am getting the following result in Paraview. Diffusion_image_oct_23_2021.png One main goal is to obtain the dat file either with the &...

Hello to all of you, I have been trying to put to work the advection diffusion solver for a minimum working example of just diffusion transport, this is with NO convection, in a cube with the respective diffusive constant and body force calculated to have the apropiated diffusive length. However, th...

Hi,

The previous attchment can be open in ElmerGUI, the file attched now can be open in the ubuntu editor.

Thanks and looking forward to an answer,

John.

Hello,

I attached the sif file. According to the error message something is not define in the solver, apparently is the Advection diffusion solver. In the sif file, the noncompressible fluids are Phole and Nelec.

Thanks and looking forward to an answer.

Hello, Thank you for your answer. Besides the Pfluid, I have other solver for another noncompressible fluid, Nfluid, symilarly as for the first one, I want just to simulate the diffusive transport. When I run the code I got the following optimization messages about the Advection Diffusion Solvers, O...

Hello, I am using the advection diffusion solver just for a diffusive transport and noncompresible fluid. I coded this solver as follows, Solver 2 Equation = "Advection Diffusion P" Variable = String Pfluid Procedure = File "AdvectionDiffusion" Nonlinear System Max Iterations = I...

Hello, I am trying to use the Nonphysical Mesh Adaptation Solver to change the lenght of two boundaries according to the physical model. However, it appears the following error message once it is run the code. Load: FATAL: Can't find procedure [nonphysicalmeshsolver_] ¿How can be installed the nonph...
