Pavel SEMTEC IM tutorial
Posted: 28 Feb 2018, 16:27
Hi,
I am trying to simulate pavel's tutorial using ELMER. I have a question regarding Multi-Slice Simulation, i have given following commands in my Virtual machine
ns=4
slen=0.04
# make rotor and stator elmer meshes from geo files
gmsh gmsh/im_stator.geo -2 -o im_stator.msh
ElmerGrid 14 2 im_stator.msh -2d -autoclean -names
gmsh gmsh/im_rotor.geo -2 -o im_rotor.msh
ElmerGrid 14 2 im_rotor.msh -2d -autoclean -names
# unite and scale to SI
ElmerGrid 2 2 im_stator -in im_rotor -unite -autoclean -names -out im
ElmerGrid 2 2 im -scale 0.001 0.001 0.001
# create slices
ElmerGrid 2 2 im -out imms -clone 1 1 $ns -clonesize 0 0 $slen
ElmerGrid 2 2 imms -partition 1 1 $ns
cp im/mesh.names imms/mesh.name
After making imms folder,i tried to run transient.sif file after first iteration it gave the error
'' WARNING:: LevelProjector: Projector % InvPerm not set in for dofs: 48
RotationalInterfaceMeshes: You might try to switch master and target!
ERROR:: RotationalInterfaceMeshes: Check your settings, this cannot be periodic!
Note: The following floating-point exceptions are signalling: IEEE_DENORMAL''
How can i deal with this?
secondly, i in tutorial it is mention that ''The last ElmerGrid command -partition 1 1 $ns creates 1 partition per slice (you can check the result of slicing in ParaView by using ElmerGrid with the second parameter 5)''. According to my understanding i change the command like '' ElmerGrid 2 5 imms -partition 1 1 $ns'' and for the next i changed partition seconed parameter to 5, but i got nothing. I am very confused in that please guide me to resolve this issue.
Thanks
