Limitation on number of blocks of block model

[m-sb]

Hi @Tim-Evans-Seequent ,

I am trying to create omf file containing blockmodel data. Had taken use of provided examples in this project.

I am trying to add almost 19000 blocks data inside the blockmodel.

Consider following code:
OmfRegularSubblocks subblocks = omf_regular_subblocks_init(4, 4, 4,
omf_writer_array_regular_subblocks(writer, REGULAR_SUBBLOCK_PARENTS, REGULAR_SUBBLOCK_CORNERS, numBlock));

Following arrays with size numBlock ie. almost 19000:
-REGULAR_SUBBLOCK_PARENTS
-REGULAR_SUBBLOCK_CORNERS

I followed all the steps to create the omf file with this blockmodel(ie. added category data, grid data etc.)

My query is there any limit on the number of blocks to add in blockmodel data structure?

Thanks in advance

OMF2 doesn't set any limits there. Software importing the file might have its own limits though. 19000 block will be nowhere close to those limits, but they will vary based on the application domain. Within the mining domain for example, 10 or even 100 million blocks will be possible.

Hi @Tim-Evans-Seequent ,

I am able to save our block model to the omf file (if our model does not contains superblock).

Query - Currently facing one issue with saving superblock into the omf file.
What is superblock - it is a block formed by combining all the childrens if they have same attribute value. in that case superblock may have block size greater than the user block size.
Do you have any suggestion on this? How to save it to the omf blockmodel file.

Thanks.

OMF doesn't support super-blocking. You would need to split those blocks up down to the user block level, and merge blocks on import based on the attribute values.

For re-import you could maybe add a "superblock id" attribute where all blocks created from one super-block would have the same value. Other software would be free to ignore that column though.

Thanks @Tim-Evans-Seequent ,

now we are able to export our model to OMF format and load the OMF type of blockmodel.
