Re: Error: Insufficient space in Bsend buffer

Hi Peter,

I ran the test with/without change a couple of times, your suggestion fixes the problem.

Re: Error: Insufficient space in Bsend buffer

Found the line with a debugger.

SParIterComm.F90, Line 4628:

Code: Select all

     IF ( L(j) > 0 ) THEN
        CALL MPI_BSEND( VecL(1:L(j),j), L(j), MPI_DOUBLE_PRECISION, &
                 J-1, 6001, ELMER_COMM_WORLD, ierr )
     END IF

Re: Error: Insufficient space in Bsend buffer

Hi Peter, I am back with the issue and, this time, with more info. The same problem happens on Windows and Linux, and does not matteron compilation Recompiling in debug mode does not give the exact place where the error happens. This is the output from Elmer: List_ToCRSMatrix: Matrix format changed ...

Re: Difference between Circuit and MagnetoDynamics currents

This does not make a difference in my case. Changing time-stepping schemes worked for cases with lower frequency, but this high-freq still has these oscillations. Making smaller timesteps seems to make things even words.

Transient WhitneyAV I(U) oscilations

Hi, Transient WhitneyAVSolver simulation with circuits. The same case is solved two times - by setting 1) current we should get voltage 2) voltage we should get current Screenshot_9.jpg Screenshot_1.jpg It seems that by setting the current, the solution is more stable. However, when setting voltage,...

Re: Axis Symmetric post processing

How about creating a new field in the calculator
coordsX*A
where instead of coordsX put the proper variable that represents the distance from axis?

Visualizing mean average value for each body

Hi, I want to calculate the mean/average value for a field (e.g., joule loss) within each body separately and save it as a field. I intend to use it to validate the homogenization model. Potential solutions I identified: 1) Using SaveScalars with many different masks, applying mean operation on them...
