Finds which saved mesh entity corresponds to a current mesh entity.

When rereading variable values from a file, we assume that the current mesh is not necessarily the same as the saved mesh. In this case, the uniqueIds of the entities do not match. Therefore, we must find which saved entity corresponds to each current mesh entity. To know which one to use, we take the one from the original mesh closest to the current mesh. Since only initial coordinates are saved, this only works correctly during initialization. This processing should not be done during restart. This information is therefore saved in a variable. TODO: It would be necessary to be able to use an algorithm other than just the closest entity.

◆ open()

void Arcane::Hdf5VariableReaderHelper2::open ( bool is_start )

Opens the file containing the reading information.

is_start is true when starting a case. If not, there is no need to read the initialization variables.
