Sleipner CO2 .data won't run

[RPH3]

Hi, I've just started investigating Flow and was interested in running the Sleipner CO2 flood dataset. I'm running Flow 2023.4 on an Ubuntu set of on a PC (v22.04.3). The file seemingly gets read OK but then dies at the first timestep with the work "Killed" as the only console output (console image attached). There is no user input at that stage. The PRT file doesn't see that but does write as far as saying it 's on time step zero. Is this an issue that anyone has come across before. The manual is pretty silent on cases killing themselves.

Hi,

Thanks for reaching out. As seen in the console output ("Processing grid, Total number of active cells:"), the Sleipner data set has on the order of 1.98 million active cells, and typically requires at least 10-12 GB of RAM to run comfortably. Usually more if you're running the case in parallel. Although it doesn't say in your output, the "Killed" message may be generated by the operating system because you're running out of memory. Flow fundamentally expects that the host system has "enough" memory available and is not set up to deal with low-memory situations. For what it's worth, Flow does not generate the "Killed" message itself.

Thanks Bård, That makes perfect sense. I have a memory upgrade planned for the machine in question but right now it’s just 8Gb. I’ll give it another go once I’ve installed the memory and see if it’ll run. Thanks for the very rapid response.
