As the simulation models grow in size, the requirements on processing resources and memory are increasing. ResInsight have some options that can improve performance by transformation of data or reduction of data input.
Summary data is usually available as SMSPEC and UNSRMY files. UNSMRY files are stored in a binary format, and all data for one time step is stored one section. When extracting data for all time steps for a single summary vector, data must be read from multiple sections. This can give bad performance for large datasets.
For best performance, transform these data files to ESMRY File Format
ResInsight has two grid import readers, ResData and opm-common. For best performance, use opm-common.
Active cells is often a small subset of total number of cells in a grid model. When this mode is activated, all inactive cells are skipped. Only geometry for active cells is imported, and all operations related to grid computations will perform better.
