Sorry about my typo in the commit statement. I meant the option was "READ_DELETE". It is a typo only in the commit statement.

Thanks for the update. Actually, ACIS parallel mesher is only working with "read_delete" method which doesn't need geometry distribution and then, can not be used when compute nodes in parallel computer can not read geometry. Anyway, I'd like to say your work is very worth for me. Thanks. ----------------------------- Hong-Jun Kim Post-doc researcher MCS, Argonne National Laboratory 9700 S.

Hi, Hong-Jun I am still doing code change for the attribute read/write stuff. it seems not a small change. The past week, I tried different things and made work for this case, then fail on the other case. But I am going to continue to work on it, trying new thoughts based on my understanding of details on OCC topology/geometry structure. I am glad that you found ACIS works for your parallel work.
