Hi,<\/p>\n

 <\/p>\n

I’m looking for some specific guidance on how to approach resolving the following problem.<\/p>\n

I’m modeling a solenoid and want to do a paremetric analysis of various plunger and spring configurations, so I’m attempting to set up the transient model. I have run into a road block with several meshing errors that I can’t work around. I assume there is a solution with clever meshing but I am not very experienced in creating my own meshes. Looking for input on how to proceed \u270c…<\/p>\n

 <\/p>\n

Image of the model: <\/p>\n

In the above image the band is causing the solver to throw an error due to it being a true surface, which I know I have to solve by converting it to a polyhedron, but of what # of slices? I have tried, 6, 24, and 120 sided polyhedrons and in each case there are different error as a result. In general I receive <\/p>\n

“[error] Error in mesh mapping on band, please check the potential problem in band setting.”<\/h4>\n

 <\/p>\n

<\/p>\n

Here’s a closer look at the motion band when I apply a Hexagonal polyhedron, to show the relative positiong of the plunger inside of the band. The solenoid is only pushing so I only intend to operate in the -x-axis. One error indicated that the mesh couldn’t be solved near the Origin, so I’m curious if that means the band and contents are too close together or maybe the band is too close to the other objects. (It returned some coordinates that were all <1mm from 0,0,0).<\/p>\n

Altogether I’m pretty limited in terms of my ability to expand the band because it would intersect with the stationary pole plate (occupying space to the left of the origin) and the bobbin (which I can remove if absolutely necesary). <\/p>\n

Can anybody give me some thoughts on where to go next?<\/p>\n

 <\/p>\n

Thanks,<\/p>\n
