memory access exception when re-partitioning

Alberto Damas · January 7, 2016, 16:20

Hi. I am working with a wind turbine using macros. When I do mesh refinement and run again (I reset and initialize interface between rotation and static regions before run) I get a memory access exception. I don't know why it happens.

I solve the problem just saving it after refinement, closing and opening again the simulation and run. The problem is that it all takes a long time and I want it goes on just with the macro without any action. Which could be the problem? I don't understand why opening again solve this.

I have found running with only one processor it works fine. Anyone who knows how could I work with more than one processor?

Thx.

Sometimes the partitioning can fail. Try using either 1 more or 1 fewer cores and see if that fixes it for you.
