After I created a block by associating the edge to the geometry(points, lines) and saved.

When I'd like to open this file again, the CFD show me a message as follow:

--------------------------------------------------------

Loading blocking file "D:/fishbone_block.blk"

no such command: 1216

error reading file D:/fishbone_block.blkError in opening Blocking file;

--------------------------------------------------------

Neither I import blocking solely or change the file path, the CFX always show me this message above.

This means the block I've created was invalid.

I create a simple block then saved, but the massage still generate.

How do I solve this problem? Thank you.

The problem was solved.

I found some improper point names in the *.block.

The error geometry name resulted in the *.tin and cause the generated block cann't be read.

The problem was solved after I revised the geometry and regenerated the topology. Thank you for your help.
