Unable to allocate memory: to make array

February 2nd 2021

Problem:

I try to run a simulation, but instead of the results, I get the following error message:

Error-Messages:
Unable to allocate memory: to make array.
Not enough space
Execution halted at: 

What is going wrong here?

Answer:

The following issues can have an influence on the memory management of RAMMS:

  • Do you use a large ortho-image that you overlay? This could be the problem here. Reduce the resolution of your ortho-image and try again.
  • Calculation domain: Do you use a narrow calculation domain? If not, please have a look in the manual on how to define an ideal calculation domain (for avalanche and debris flow simulations).
  • Dump Step: By increasing the dump step, you decrease the amount of memory needed to open a simulation file.
  • Simulation resolution: A very good (=small) simulation resolution increases the amount of memory needed to open a simulation file.
