Abaqus tutorial EP021 Topology Optimize Method 

Thanks for the tutorial! Helped me a lot

When running the optimization I get the following error message: Error in Piston_Opt-Process-1: [15:17:10.253917|tosca_python] SaveRule found that removes .odb files from working directory. Error in Piston_Opt-Process-1: [15:17:10.253917|tosca_python] Moving odb files in case Abaqus runs in simultaneous mode may cause abaqus to fail unexpectedly. Error in Piston_Opt-Process-1: [15:17:10.253917|tosca_python] To remove this warning check your SaveRules in any tosca.cfg or DRIVER command blocks loaded by this jobs and disable the offending rule. Error in Piston_Opt-Process-1: [15:17:10.253917|tosca_python] Offending rule is: Error in Piston_Opt-Process-1: [15:17:10.253917|tosca_python] config.registerSaveRule( UpdateRules.MOVE, CheckPoints.CYCLE_COMPLETE, (EventTimes.NTH, 1), [ r"*.odb" ], r"SAVE.odb", r"_%i" ) Error in Piston_Opt-Process-1: [15:17:10.254923|tosca_python] In DRIVER command of C:\temp\Piston_Opt-Process-1.par Error in Piston_Opt-Process-1: [15:17:10.254923|tosca_python] Invalid Configuration for TOSCA. Error in Piston_Opt-Process-1: [15:17:10.254923|tosca_python] Tosca Structure failed to run the optimization task , can you help me out with this?

where can i find a model file?
