hello

I tried to launch a simulation with TOMAWAC and it returned this :

someone could solve this ??

Hello,

the model you want to solve with TOMAWAC is huge!
In your model you have more than 165000 mesh nodes. Let's take 24 directions and 20 frequency for the directional spectrum discretization. In this case you have : 165000 X 24 X 20 variables to be calculated at each time step. That makes 80 million variables.

The 6.0 version of TOMAWAC is not able to deal with such a high number of nodes.
The simulation stops because there are problems in the variable allocations, i.e. in the memory management.

The 6.1 parallel version of TOMAWAC should be able to deal with such large models.

Hope it helps.
Kind regards,

Giovanni
