Memory issue after mapping
 
Hi all,

I've tried to restart a simulation using the mapping variables function (with scaling), however when starting the simulation I am getting a memory allocation error:

2512 ERROR : Memory allocation failure. Check your mem_usage.out for memory requirements of this case

However there is no such file, and I am basically running the same model as the earlier mapped one, on the same computer and it was no way near the memory limit of the computer.

What can I do?

EDIT: I have noticed that if I only scale 1 variable and remove the others from the list it works. Weird.

Hi MMatt, To initialize the domain, CONVERGE allows the user to manipulate (scaling of mapping variables) the output from a previous simulation.

To be able to reproduce your problem, please contact our support team at support@convergecfd.com.
