Re: 3D simulation of a Motor without application of a load

Hi Felix, The torque in 2D and 3D is a little different. In 2D it must be multiplied by the length of the machine even when using 2.5D approach. In 3D not. In both cases the result must be multiplied with the number of symmetric sections. Regarding BCs here are some that I've been using lately. Here...

Re: B field from wire current

Hi, Yes, the primary field for the solver is the vector potential. If we want to set magnetic flux density directly the code needs to do some non-trivial bookkeeping since the value of flux density is obtained by looping over element edges. In this case no value for AV was given so where should the ...

Re: Wrong SaveScalars convective flux

Hi Cedric, Maybe you could check to remove the SaveScalars instances that give correct solution and check whether the problematic instances still give wrong answers. Or do the result depend on which order the instances are accessed. The module should not have any memory that it was called with diffe...

Re: High order infinite loop during partition/ parallel run fails

Hi

Replace "StatElecSolve" with "StatElecSolveVec" and you may have better success.

Re: Bug in SaveScalars in parallel?

Just to note: this was fixed by Fabien.

The reason for the original bug was that the application of this routine was extended beyond nodal fields. If we have other type of fields we cannot use just the parallel info related to the geometric nodes.

Re: Elmer's solution for coupling different solvers

Hi,

We are still working on some minor issues. I think our marketing department got a little ahead of us! But great to have the visibility even though it puts some pressure on us.

Re: Model induction between two coils

Hi CoilSolver is merely a static current conduction solver with some special hacks that make life easier for coils, e.g. 1) You can define currents for closed coils without having to create an extra cut on it 2) You can normalize the current density automatically to have desired total current 3) You...

Re: Error: Insufficient space in Bsend buffer

Hi Juris,

What if you increase the size at line 4602. E.g. to
CALL CheckBuffer( 8*TotalL + ParEnv % NumOfNeighbours*(1+MPI_BSEND_OVERHEAD) )

Re: Storing an variable from UDF at each iteration step

Hi Eric,

What is the size of your variable?

Are you sure that your case is an UDF rather than a Solver. If you have transient history then the Solver provides some services to advance a variable forward when doing timestepping. So what would the UDF do? The answer depends on your goal.
