Hi Peter, Thank you for the notes! The core loss can be calculated and saved in VTU now. I found the Exported Variable should be defined in the Solver section "MagnetoDynamics2D", instead of the defined solver "CoreLossSolver". Otherwise, the size of the exported variable is not ...

Hi Peter Thank you so much for the advices! I have tried the FourierSolver, but it calculates the loss at least after one or several rotational periods. Actually, I want to optimize the motor with less calculation cost. Hence, I tried the time-step method to calculate the hysteresis loss and eddy-cu...

Hi Peter, Thank you again for your replay. For the 2D magnetic field, actually I only need the norm value (scalar value) of magnetic flux density of each nodal. Now, I tried to find corresponding variable Bx and By in MagnetoDynamics2D.F90 or CalcFields.F90, but I am not quite sure about that I have...

Hi Peter Thank you so much for your helpful response. It works to creat a new variable in sif file. However, I find that the defined variable has different size with other mesh variables, i.e. the magnetic vector potential A or flux density. For instance, in sif file I defined the variable Ph: Solve...

Hi, Dear Elmer developers I am a motor designer, and I try to develop my own subroutine to calculate the core loss of the electrical steel. Now, I do not know how to output the calculated field of core loss into the vtu file, so that it can be visulized in ParaView? Actually, I have read the source ...

Hi guys, I have solved the problem, after I slightly modified the source code in the file "CalcFields.F90". An additional subroutine is added and can be called by the subroutine "MagnetoDynamicsCalcFields". Now, the solver can also solve the electromagnetic force acting on the st...

Hi, I am anlyzing the force acting on a rotor of the switched reluctance motor in a 2D transient model. The solver "MagnetoDynamics2D" is used to solve the potential, and the "MagnetoDynamicsCalcFields" is used to extract the distribution of flux density, and also the magnetic to...
