Re: Calculation of the area of a boundary before simulation
Yes, Finally I made calculations of the area of a body surface in 2D domain and saving it with other scalars by Solver 5 Exec Solver = After Timestep Filename = "scalarsEMF2.dat" Procedure = "SaveData" "SaveScalars" Show Norm Index = 1 ! Calculation of the volume of a b...

Re: Calculation of the area of a boundary before simulation
Hello, Peter, For me it is logical to access such scalar data via SaveScalars. Maybe a new Operator could be introduced to access individual body (material, BF..) weights? It also looks logical taking into account possibility of mesh changes during simulation due to e.g. Mesh Adaptation Solver. So, ...

Re: Calculation of the area of a boundary before simulation
Helo, Is there a way to elegantly save body weight of a specific body to the file e.g. using SaveScalars? I have found in this post http://www.elmerfem.org/forum/viewtopic.php?f=3&t=3320 a method which utilizes dummy variable introduced within a body by a dummy solver just to compute the volume ...

Re: Periodic boundaries and sliding surface
Hello, I have tried simulation with higher values of "Interpolation Numeric Epsilon" and without"explicit" flag. Still, the same results -- wrong flux density at these two points in the sliding surface at 0 and 180 degrees. Maybe you could give some recommendations how to avoid s...

Periodic boundaries and sliding surface
Hello, I have nonphysical behavior when I impose anti-periodic boundary conditions in my model in MagnetoDynamics2D. Here is my domain with indicated boundary indices. https://dl.dropboxusercontent.com/u/542224/temp/boundaries.png And here is the solution. https://dl.dropboxusercontent.com/u/542224/...

Re: Calculation of the area of a boundary before simulation
Thank you, And a follow up question: Is this normalizing works for each body enumerated in "Target Bodies" separately, or it normalizes over the combined area of all these bodies? ... !current in the phase U+ Body Force 2 Name = "Current_U_plus" Current Density = Variable time, t...

Calculation of the area of a boundary before simulation
Hello, Is there a way to calculate in-line in the SIF the area of a face on which I impose a body force? In my case (in MagnetoDynamics2D in an optimization loop where geometry is constantly changing) I know the total current to penetrate in Z-direction through a face as body force, however I do not...

Re: Parallel Whitney, MGDynamicsCalc: distorted results
Hei, I have observed also distorted results in parallel with MagnetoDynamics2D. The potential was calculated correctly, but flux density was distorted in the air gap region of simulated electrical machine. https://dl.dropboxusercontent.com/u/542224/distorted.png This resulted in completely wrong est...

Re: Eddy current in wire
Hi The Whitney solver is by construction only 3D. There is a 2D solver MagnetoDynamics2D that should do almost the same things in 2D. However, the 2D case is much more simple as all the physical phenomena are not present. How is the eddy current introduced in 2D if not by rotation (as in: http://yo...
