Title2 in d3plot header

[MatthieuDebray]

According to Lasso D3plot_header documentation, there an optional 2nd title store in header.title2 But, it seems to not stored when we wrote the d3plot. Does this 2nd title is define in d3plot format ? My objective was to store some additional string info inside the D3plot (not obliged to be in the title) Thanks for help

Writing Issue found : in d3plot.py on function _write_header_part_contact_interface_titles

line :if "title2" in self.header.title2 should be replaced by something like : if self.header.title2 and isinstance(self.header.title2,str):

Nevertheless, I would propose a new function to retrieve header and geometry data without loading all d3plot We can read just the header using : header = D3plotHeader(d3plotFile) But this header will not get title2 as it's read later by _parse_geometry What would be the best way to do this?

• If you use the state filter option and leave it empty it should not load state data into memory
• Why do you want to check title2 for string? If it is an empty string why bother writing it? It is no issue to change it either way I'm just curious.

Hello Codie, Thanks for tips, doing that : d3plot = D3plot(d3plotFile,buffered_reading=True,state_filter=[0,],state_array_filter=[])it's fast to get title2. I put a check for string, because if somebody do this title2 = 1. Maybe it's not needed if after your code will not expect a string.

It is python so while it is tempting to verify this I do not recommend it. This is within the domain of "you will get punched in the face if you do something very silly".
