Cosmos, surface not defined in SL1 file

Dominic Baker Jan 7, 2007 8:10 PM

Hi I am making a bolted assembly, normal bolts are fine, but these countersunk ones are a pain. I made little countersunk inserts to sit in the holes to give a flat surface. Now the error message comes up saying 'Source surface not defined in SL1 file at bolt Conn. ID7'
I supressed bolt conn 7 and even deleted it remeshing each time, but no use. What is an SL1 file? any ideas of what might be wrong.

One suggestion: unless you need info from specifically around the bolted area, you might want to use a pin connector instead of actually placing the bolts in there. This doesn't address your problem directly, but just an idea.

As for SL1 file, I have had that message come up when one of my connectors 'loses' a face. So go through and view all of your connectors and conact constraints to see if one of them is missing a face. I have had them just disappear on me for no reason.

    It would be more helpful if you provided a link to your similar posting so that we could find it easily. I still don't know what the SL1 file is and why my simulation fails with this error. Wow, almost 6 years later and seeing the same bug! Really??
