open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi, I have tried to run my ARTEMIS model however am getting the following error message:

Any ideas what this error is related to and how to resolve it?

Hello,

I may be wrong but it looks like a memory allocation problem. With ARTEMIS, when you use the DIRECT solver (=8), you need a lot of memory. On Windows you have to declare the anticipated memory a program will take at the compilation stage: using /stack:536870912 in the cmd_exe value of your configuration.

First, if you run large ARTEMIS simulations with DIRECT solver, do make sure you use a 64bit compiler on a 64bit Operating System.

Second, you need to up the size of /stack:536870912 .. a multiple of 2 could help.

Third, if you cannot do this, do not use the DIRECT solver. The calculation will be slower but less memory hungry.

Forth, if you still have trouble, do send us your cases so we can test on our windows systems.

Hope this help.

Sébastien.

Thanks Sebastien, I managed to solve that problem but now I am getting another error and can't figure out what is causing it. I have attached a screenshot of this message along with my model files.

Thanks for your help,

Niamh
