I understand that the ‘find_system’ function with the ‘MatchFilter’ option allows you to filter blocks based on a custom function. In your example, you are using the ‘nonInOutBlocks’ function as a filter. However, if 'blks' is empty, it suggests that there might be no blocks in the system that match the criteria.
Try a simpler ‘MatchFilter’ function, if it works, then the issue might be specific to the ‘nonInOutBlocks’ function definition.
You might want to check the block types in your system and adjust the filtering criteria accordingly. You can use the ‘get_param’ function to inspect the properties of a block and modify the ‘nonInOutBlocks’ function accordingly.
