Cannot map voxel …

The loads and boundary conditions could not be mapped to the voxel model and might not be considered in the optimisation anymore. LBCs should always be applied to Non-Design Spaces. These ensure a correct consideration of the LBCs during the optimisation.

This might occur while performing a Command Line optimisation. While the SwitchAddRemove (schedule.iterations.OutputDuplicateInErode.outputMode, schedule.iterations.OutputDuplicateInGrow.outputMode) option is active only every second iteration is visible as an result. In this case the iteration could not be copied but the optimisation will continue. To remedy this situation delete the output folder and start the optimisation anew.
